In political geography, an enclave is a piece of land which is totally surrounded by a foreign territory. An exclave is a piece of land which is politically attached to a larger piece but not physically conterminous with it because of surrounding foreign territory. Many entities are both enclaves and exclaves.
In China:Chaoyang District has one exclave which comprises Terminals 1 and 2 of Beijing International Airport and the immediately surrounding service area. It is an enclave of Shunyi which used to be Shunyi Subdistrict of Chaoyang District. The main reason for the existence of this exclave is because the financing for the building of these Terminals was largely carried by Chaoyang District and this political organization ensures that they continue to pay taxes to Chaoyang District. Note: Terminal 3 is not a part of this exclave as it was built for the 2008 Olympics and was built after the formation of Shunyi District. See a map of the exclave, not including Terminal 3, on Google Maps.In Estonia:In Ida-Viru County, the town of Kohtla-Järve consists of seven separated areas within a distance of 30 km.

Semi-enclaves and semi-exclaves are areas that, except for possessing an unsurrounded sea border, would otherwise be enclaves or exclaves. Semi-enclaves can exist as independent states that border only one other state. Vinokurov (2007) declares, "Technically, Portugal, Denmark, and Canada also border only one foreign state, but they are not enclosed in the geographical, political, or economic sense. They have vast access to international waters. At the same time, there are states that, although in possession of sea access, are still enclosed by the territories of a foreign state." Therefore, Vinokurov applies a quantitative principle: the land boundary must be longer than the coastline. Thus he classifies a state as a sovereign semi-enclave if it borders on just one state, and its land boundary is longer than its sea coastline. Vinokurov affirms that "no similar quantitative criterion is needed to define the scope of non-sovereign semi-enclaves/exclaves."
BruneiGambiaMonacoBrunei: Temburong District is bounded by Malaysia and Brunei Bay.Cyprus (de facto): The de facto independent Turkish Republic of Northern Cyprus (TRNC), which is unrecognized internationally, has a semi-enclave in the island's Northwest, Kokkina/Erenköy, which is bounded by the U.N. buffer zone and the Mediterranean Sea.East Timor: Oecusse is bounded by Indonesia and the Savu Sea.Oman: Musandam is bounded by the United Arab Emirates and the Strait of Hormuz.Spain: Ceuta, Melilla, and Peñón de Vélez de la Gomera are bounded by the Mediterranean Sea and by either a neutral zone or Morocco itself.United Kingdom:The overseas territory of Gibraltar is on the south coast of Spain.

Such areas are enclaves or exclaves for practical purposes, without meeting the strict definition; hence they are also called functional enclaves or practical enclaves. Many pene-exclaves partially border their own territorial waters (i.e., they are not surrounded by other nations' territorial waters). A pene-enclave can also exist entirely on land, such as when intervening mountains render a territory inaccessible from other parts of a country except through alien territory. Thus, a pene-exclave has land borders with other territory but is not completely surrounded by the other's land or territorial waters. They can exhibit continuity of state territory across territorial waters but, nevertheless, a discontinuity on land, such as in the case of Point Roberts. Along rivers that change course, pene-enclaves can be observed as complexes comprising many small pene-enclaves. Attribution of a pene-enclave status to a territory can sometimes be disputed, depending on whether the territory is considered to be practically inaccessible from the mainland or not.
Austria:The municipality of Jungholz is connected to the rest of Austria at a quadripoint at the summit of the mountain Sorgschrofen (1636 m). Road access is only via German land. However, Vinokurov (2007) states, "For all purposes, a connection in a single point does not mean anything. It is just like being completely separated. One cannot pass through a single point, nor is it possible to transport goods. It is not even possible to lay a telephone line." (See above: Enclaves which are also exclaves.)The Kleinwalsertal, a valley part of Vorarlberg, can only be reached by road from Oberstdorf, Germany.Hinterriß and Eng (parts of the communes of Vomp and Eben am Achensee in Tyrol, Austria) are functional exclaves accessible by road only from Germany.Belgium/France: Along the river Leie (Lys in French) between Halluin and Armentières, where the river forms the border, there are 7 small pene-exclaves of Belgium (province of Hainaut) on the southern side of the river and 7 small pene-exclaves of France (department of Nord) on the northern side of the river. This is due to minor changes in the course of the river since the border was fixed in 1830.Belgium/Netherlands: On the Dutch side of the Meuse River, between the Belgian municipality of Visé and its neighboring Dutch municipalities of Maastricht and Eijsden-Margraten, Belgium has two pene-exclaves, Presqu'ile de L'Ilal and Presqu'ile d'Eijsden. A Dutch pene-exclave, Presqu'ile Petit-Gravier, lies on the Belgian side. The two heads of state signed a treaty in 2016 to swap these plots of land, which are the result of river straightening prior to 1980.Belize: Ambergris Caye is an island in Belize located south of the Mexican state of Quintana Roo.

Connection with the rest of Canada is by ferry.The Haskell Free Library and Opera House is on the border between the United States and Canada. The Canadian part of the building is a practical exclave of Canada, as most of the building is physically in Stanstead, Quebec, but the only public access to the building is via the front door on Caswell Avenue in Derby Line, Vermont, in the United States. (Emergency exits from the second floor open to Canada.) People in Canada may not enter or exit the building except by travelling into the U.S. A special exception allows library and opera house patrons to cross the border to enter and move about in the building, but they must return to their home country (or see the Customs office) to avoid being charged with illegally entering the other country.Croatia: The southern portion of Dubrovnik-Neretva County, including the historic city of Dubrovnik, is bounded by Bosnia and Herzegovina, Montenegro, and the Adriatic Sea. Neum, Bosnia and Herzegovina's only sea access, is sandwiched between the two portions of this county. This pene-exclave relies on national territorial waters as its only alternative connection to the rest of the country."Denmark/Germany: Several farms on the border.Finland/Sweden: The Finnish municipality of Tornio has one pene-enclave unreachable directly by land from Finnish territory, although connected to the rest of the city by a pair of bridges. The neighboring Swedish municipality of Haparanda has two similar pene-enclaves unreachable directly from Swedish territory. One is an islet crossed by the international border at a golf course on the line between Tornio and Haparanda.France: The territorial water of Canada completely surrounds that of the French territorial collectivity of St Pierre and Miquelon except for a corridor 10.5 NM (19.4 km) wide stretching 200 NM (370 km) south to open sea.Germany/Switzerland:The smaller part of the German city of Konstanz, which includes the Aldstadt (old town), lies to the south of the Rhine and has no land border with Germany, being otherwise surrounded by Switzerland; it is linked to the rest of Konstanz, and by extension to the rest of Germany, by a bridge.The Swiss town of Stein am Rhein has only a bridge over the Rhine connecting it to the rest of Switzerland, which it does not border on land, and is otherwise surrounded by Germany.Guatemala/Mexico: The changing course of the Río Suchiate has created pene-exclaves on both banks of the river.Indonesia:On the island of New Guinea, West Papua is surrounded by Papua New Guinea, the Arafura Sea and the Pacific Ocean;Borneo's subdivisions include a part of Malaysia (the states of Sabah and Sarawak) and a part of Indonesia that are conterminous; thus, each part is a pene-exclave of its home country.West Timor is surrounded by East Timor, the Timor Sea and the Savu Sea.Ireland/United Kingdom: The western-most region of County Monaghan in Ireland contains a pene-enclave jutting into County Fermanagh, United Kingdom, known as the Drummully Polyp or Salient (also locally as Coleman Island after the name of its northernmost townland, Coleman). There are two inaccessible districts: Drumard in the 'polyp' itself, belongs to Ireland and is inaccessible directly by road from any other part of Ireland; the village of Summerhill, County Fermanagh in the United Kingdom is similarly inaccessible from the rest of the United Kingdom. The A3 (UK) and N54 (Ireland) road, known as the Concession Road, crosses the border here 4 times in a short distance.Italy:The Livigno valley near the Swiss border was at one time accessible only from Switzerland and was exempt from Italian customs, an exemption that continues today even though road access to the rest of Italy has been established. It is therefore excluded from EU VAT area.The village of Bagni di Craveggia can only be reached by travelling through the Canton of Ticino in Switzerland. The village never became part of Switzerland, as the pastures surrounding it were owned by the people of Vigezzo Valley, rather than the people of the Swiss Onsernone Valley, at the end of which the village is situated. Consequently, the Swiss franc is commonly used.On the San Marino/Italy border, there is Italian land east of the River San Marino that does not join to any other part of 'dry' Italian territory. This area is only a few metres wide, and follows the river's course for around 500 metres, and is close to the Strada del Lavoro.Laos: Many places, usually restaurants or markets, can only be accessed from Thailand by boat and do not require passports to enter.Lithuania: Curonian Spit's northern part in the Klaipėda District is bounded by Russia and the Baltic Sea, but has the common territorial waters of Lithuania.Mexico/United States of America: Shifts in the meandering course of the lower Rio Bravo del Norte (Rio Grande) have created numerous pene-exclaves. Under the Boundary Treaty of 1970 and earlier treaties, the two nations have maintained the actual course of the river as the international boundary, but both must approve proposed changes. From 1989 to 2009, there were 128 locations where the river changed course, causing land that had been on one side of the river to then occupy the opposite bank. Until the boundary is officially changed, there are 60 small pene-exclaves of the state of Texas now lying on the southern side of the river, as well as 68 such pene-exclaves of Mexico on the northern side of the river. The last such exchange (of pre-1989 river cuts) occurred in 2009, after languishing as a proposal for 20 years.Malaysia: In the state of Sarawak on the island of Borneo, the Limbang Division is completely cut off from the rest of the state's road network. The Limbang District in the division is only accessible by road through Brunei, as it is located between Brunei's main portion and the Temburong District. The Lawas District, on the other hand, lies between Temburong and the state of Sabah. As Sabah and Sarawak have autonomy in immigration affairs, immigration checks are required when traveling into or out of the Limbang Division by road.Myanmar: The town of Payathonzu can be accessed from Kanchanaburi, Thailand by road. It cannot be reached by road from other locations in the country.Namibia: Mpalila Island can only be reached from the rest of the country by travelling through Botswana.Netherlands: Part of the province of Zeeland, namely Zeeuws Vlaanderen is accessible by land only through the country of Belgium, although it is accessible by sea from the rest of the province of Zeeland. There is a tunnel, the Westerscheldetunnel, which also links Zeeuws Vlaanderen to the rest of the province.North Korea:A small pene-exclave is located on a lake island that is divided between North Korea and Songsan-ri, Paju-si, Gyeonggi-do in South Korea. It can be accessed by boat only.Another pene-exclave is located on the south side of a river adjacent to Gadal-ri, Cheorwon-gun, Gangwon-do in South Korea. It can be accessed by boat only.Norway/Sweden: Properties 79/3 and 79/4 at Trosterud in the Norwegian municipality of Rømskog are only accessible by a road that follows the Norwegian–Swedish boundary.Portugal: An area north of Tourém is cut off from the rest of Portuguese territory by the lake Encoro de Salas, being surrounded by Spanish territory. It is accessible by a road bridge, but otherwise does not border the rest of Portugal.Russia:Dubki area is bounded by Estonia and Lake Peipsi-Pihkva.The settlement of Maloje Kulisko is separated from the rest of the country by the Kuuleski River; the village is otherwise surrounded by Estonian territory, although as it is a bog island, it is not accessible from Estonia either.Vistula Spit's eastern part in the Kaliningrad Area is bounded by Poland and the Baltic Sea, but has the common territorial waters of Russia.Senegal: An area of marshy land, approximately 1-mile (1.6 km) south of Tiong, Mauritania is owned by Senegal, but is inaccessible from any other part of Senegal. Coastal waters, however, are contiguous.Spain: Os de Civís is inaccessible via any other part of Spanish territory, as one has to travel via Andorra.Togo: A territory in the northwestern end of Togo is only accessible through Burkina Faso.Turkey:The European section of Turkey is bounded by Greece and Bulgaria. Despite that the European section and the Asian sections of Turkey are not geographically conterminous and are separated by international waters, there are two connecting bridges in Istanbul.The valley of Macahel, which includes five villages in northeastern Turkey, can only be reached by vehicle via Batumi in Georgia. In winter, as the snow shuts the paths that are completely within the borders of Turkey, the road via Batumi is the only way to travel there.Turkey has a pene-exclave west of the Maritsa River opposite Edirne (Adrianople), with a land boundary of 10.8 km with Greece.Uganda: The extreme tip of Tanzania's Kanyiragwa peninsula is a very small pene-exclave of Uganda on the shore of Lake Victoria, created by the parallel of latitude that defines most of the border between Uganda and Tanzania.United Kingdom: Northern Ireland is bounded by Ireland, the Irish Sea and the Atlantic Ocean.United States of America/Canada:Although Alaska is itself a pene-exclave (road access is primarily via the Alaska Highway), the town of Hyder, Alaska, can only be reached by road from Stewart, British Columbia. There is no road from Hyder to any other point in Alaska. Additionally, much of the Alaska Panhandle consists of mountainous peninsulas; many communities along the coast lack road connection to other parts of Alaska directly, such as the state capital, Juneau.Point Roberts, Washington, is bounded by British Columbia, Canada, the Strait of Georgia, and Boundary Bay. It can be reached from the rest of Washington State only via road through two border crossings.A small unnamed peninsula in North Dakota in a lake northwest of the town of St. John, southwest of Lena, Manitoba and just south of Gunnville Lake, Manitoba.The Northwest Angle – the northernmost part of Lake of the Woods County, Minnesota, and the northernmost part of the contiguous 48 states – is bounded by Manitoba, Canada and Lake of the Woods. Access to the rest of Minnesota is only via boat or by a pair of vehicular border crossings.Elm Point, Minnesota and two small pieces of uninhabited land just to its west (Buffalo Bay Point) are also bounded by Manitoba and Lake of the Woods.The Alburgh Tongue in Lake Champlain, location of the town of Alburgh, Vermont, is bounded by Quebec, Canada to the north. The community can be reached via road bridges from Vermont or New York.Province Point, the small end of a peninsula east of Alburgh, Vermont, is bounded by Quebec and Lake Champlain.Estcourt Station, Maine, does not have public road access to the rest of Maine. Instead, Estcourt Station's houses, store and gas station access Rue Frontiere, a street on the Canadian side of the border in Pohenegamook, Quebec.Divided islands

The unusual border consists of eight line segments and takes the form of an inverted 'S', with the island's lighthouse connected to the rest of Finland only by a short stretch of land.Kataja Island (Inakari in Finnish) is divided into two pene-exclaves, one of each nation. It was formed by the merger of two smaller islands due to post-glacial rebound.Finland/Russia:Koiluoto Island, located in the Gulf of Finland in the Baltic Sea, is divided by the two nations; hence, it consists of a pene-exclave of each.The two nations also each have pene-exclaves on ten divided islands in lakes on their international border.Indonesia and Malaysia: Sebatik Island, a satellite island of Borneo, is divided between the two states.Ireland/United Kingdom: The islet of Pollatawny 54°32′40″N 8°0′25″W in Lough Vearty lies on the international border; hence, each nation has a pene-exclave there.Lithuania/Russia: An island in the Šešupė River is divided between Lithuania and the Kaliningrad Oblast of Russia.Norway and Russia each have pene-exclaves on two divided islands and one divided islet in two lakes on their international border.Norway/Sweden: On their international border, Norway and Sweden divide 16 lake islands and one river islet into pene-exclaves of each nation.Poland and Germany divide Usedom Island, in the northern part of the Szczecin Lagoon.St. Martin/Sint Maarten in the Caribbean Sea are pene-exclaves of France and the Kingdom of the Netherlands, respectively.Turkey:The tripoint junction (41°42′40″N 26°21′28″E) of the borders of Turkey, Greece and Bulgaria is on an island in the Maritsa River known as Kavak Ada or Évros Alpha. Thus it contains three pene-exclaves.Turkey and Greece divide an island in the Maritsa River known as island Q located at 41°20′10″N 26°36′50″E, thus each nation has a pene-exclave there.United States of America/Canada: The two nations share extremely long borders defined by two meridians of longitude and the 49th parallel of north latitude, crossing many lakes and rivers and, in at least 44 locations, dividing many islands. Each divided island contains a pene-exclave of each nation:Canada and the U.S. divide an island in the Columbia River at 49°0.04′N 117°38.01′W near the Waneta border crossing of Washington and British Columbia.Salt Lake in northeastern Montana, known as Alkali Lake in Saskatchewan, contains an island that is crossed by the international border at its southern tip (49°0′0″N 104°18′39.4″W). When the lake is not dry, the island forms pene-exclaves of each nation.The two nations also divide two islands on their international border in Boundary Lake, North Dakota and Manitoba. The larger eastern island lies at 48°59′57″N 100°12′47″W; the tiny western island is at 48°59′57″N 100°13′1.5″W.Each nation has a pene-exclave on the 77-acre Province Island at 45.00491°N 72.23131°W / 45.00491; -72.23131 in Lake Memphremagog, Vermont and Quebec.

The 14 river islands outside of Alaska and Yukon border the states of Washington, Montana, North Dakota and Maine (1, 7, 1 and 5, respectively) and the Canadian provinces of British Columbia, Alberta, Saskatchewan, Manitoba, Quebec and New Brunswick (1, 5, 2, 1, 1 and 4, respectively). The 15 lake islands at lower latitudes are shared by the states of Washington, Montana, North Dakota, Vermont and Maine (2, 2, 9, 1 and 1, respectively), and the Canadian provinces of British Columbia, Alberta, Saskatchewan, Manitoba, Quebec and New Brunswick (2, 1, 2, 8, 1 and 1, respectively).In Australia, although the Jervis Bay Territory, which occupies a coastal peninsula, is not part of the Australian Capital Territory, the laws of the ACT apply to it. It is administered by a department of the ACT government and is, in effect, a pene-exclave, accessible by travel through New South Wales.In Canada:The village of Atlin, British Columbia is only accessible by road through the Yukon.The village of Tungsten, Northwest Territories is only accessible by road through the Yukon.Similarly, to reach the towns of Fort McPherson, Tsiigehtchic and Inuvik in the Inuvik Region by road from elsewhere in the Northwest Territories, it is necessary to drive into Yukon and take the Dempster Highway.Cold Lake, a large C-shaped lake, straddles the border between Alberta and Saskatchewan in such a way that a peninsula in Alberta territory can only be reached overland by passing through Saskatchewan's Meadow Lake Provincial Park.In China:Most of Chongming Island at the mouth of the Yangtze is administered as Chongming County of Shanghai municipality. However, a long swath of the northern side of the island was added to the island in the 1970s from the formerly separate island of Yonglongsha. It is divided between Haiyong and Qilong townships, which are administered as pene-exclaves of Nantong's county-level cities of Haimen and Qidong, respectively. Formerly connected only by ferry, they joined the mainland's road network with the completion of the Chongqi Bridge, although all routes now pass through Shanghai's territory.The northern part of Hong Kong's Sai Kung Peninsula is a part of Tai Po District, not Sai Kung District. There is no direct road link between two areas.In Finland, the South Karelian municipality of Taipalsaari is spread across several islands and peninsulas in Lake Saimaa, many of which are only accessible by road from its neighbouring municipalities. For example, the village of Merenlahti is located on a small peninsula and the only way to get there by road is through Lappeenranta. Similarly, Taipalsaari has got five small exclaves that border Lemi and which can only be accessed from there.In Germany, the North Sea tidal island of Neuwerk off the Lower Saxon coast is a pene-exclave of the federal state of Hamburg during low tide, when one can reach it on foot or by horse carriages.In Iceland:Hafnarfjörður municipality is divided into two sections, on opposite sides of a peninsula.Skagabyggð municipality has two non-contiguous pieces with sea access.The municipality of Grímsnes- og Grafningshreppur has three sections. Two sections are connected at a quadripoint, and the third is effectively separate, although administrative boundaries are undetermined. If this section is in fact connected, then the municipality of Bláskógabyggð would be divided in two (although still connected at the aforementioned quadripoint).In India:The Union Territory of Daman and Diu consists of two coastal exclaves in the state of Gujarat. Of these, Diu Island is far away from Daman, which is much closer to another former Portuguese colony, Dadra and Nagar Haveli. However, for historical reasons these territories are separately administered.In Tamil Nadu State, the Kalakkad Mundanthurai Tiger Reserve contains 27 exclaves of the two districts of Kanyakumari and Tirunelveli.In Indonesia, the province of Yogyakarta is a coastal enclave of Central Java province with access to Indian Ocean in the south.In Ireland, the townland of Aughinish in the parish of Oughtmama is a coastal pene-exclave of County Clare, from which it can be accessed by land only by traveling through County Galway.In Italy, the southern part of the Province of Venice, Veneto, can be reached by land only by traveling through the Province of Padua.In Malaysia:Cape Rachado is an exclave of state of Malacca, which lies on the coast of Negeri Sembilan.Cameron Highlands, Malaysia's largest tea-growing region, lies in the state of Pahang but is only accessible via Tapah in the state of Perak.In Mexico: Calica and Xel-Há in the municipality of Cozumel in Quintana Roo State have two polygons of land bounded by the Solidaridad Municipality but with a coast.In Moldova, Tiraspol, the capital city of the breakaway territory of Transnistria, lies on the left bank of the Dniester River but has two pene-exclaves on the right bank inside an oxbow bend, which must be accessed on land through the Căuşeni district.In the Netherlands, the province of Overijssel has two pene-exclaves on the Gelderland bank of the IJssel river opposite the towns of Olst and Wijhe, in which the villages of Marle (northerly), Welsum and Welsumerveld (southerly) are situated.

It is however the regional center of ARMM.In SoCCSKSarGen, Sarangani province is divided by General Santos City and Sarangani Bay.In Zamboanga Peninsula:Isabela City is part of this region (although it is the capital of the ARMM province of Basilan), but it is separated from it by Basilan Strait.Zamboanga del Sur – Zamboanga City, a chartered city, is unofficially part of this province but is separated from it by Zamboanga Sibugay.In Romblon Province, the exclave of the municipality of Looc is separated by the Looc Bay forming a peninsula with neighboring municipality of Santa Fe.In Portugal, Vila Real de Santo António is divided into 3 freguesias, one of which is a few kilometers west of the other two. The "main," eastern part of its territory (where the municipal seat stands and where most of its inhabitants live) is more than three times smaller than the "secondary" part. To go from the eastern part to the western, one must pass through territory belonging to the municipality of Castro Marim, or go by sea, as all 3 freguesias face the Atlantic Ocean to the South.In the Republic of China (Taiwan), Keelung City (part of Taiwan Province) faces East China Sea on one side and borders New Taipei City (a special municipality not a part of Taiwan Province) on all other sides.In Romania, the village of Nămoloasa (Galaţi county) can be accessed only through Vrancea County (where there is a bridge over the Siret River) because it is separated by the Siret River from the rest of Galaţi county.In Russia:St. Petersburg, the administrative center of Leningrad Oblast, is a pene-enclave of it, as it has a shoreline on the Baltic Sea.Adjacent to the northwestern boundary of Moscow, there is a small exclave of the Krasnogorsk administrative district located at the 65-km mark outside of the 137-km Moscow Ring Road (Moskovskaya Koltsevaya Avtomobilnaya Doroga or MKAD), within which the administrative center and regional court are located. This area lacks access to the nearby Moscow River.In Samoa, A'ana, Palauli, Satupa'itea, and Va'a-o-Fonoti districts each have one exclave, and Gaga'emauga district has two. All parts of each district have sea access.In South Korea:Incheon Metropolitan City: Ganghwa Island is administered by Incheon, but is connected by bridges to Gyeonggi Province.Yeongjong Island, where Incheon International Airport is located, is administered by Jung-gu, but is connected by bridge to Seo-gu.

(see map).On the English side of the English/Scottish border, the hamlet of High Cocklaw is not accessible directly from any other part of England except via footpath.Newmarket is part of the County of Suffolk, but has only a small strip of land connecting it to the rest of the county and is otherwise entirely surrounded by Cambridgeshire.Scotland: There are two parts inaccessible from anywhere else other than travelling through England; these are Edrington Castle and the village of Cawderstanes, which is accessible to the rest of Scotland by footbridge only. There is also a small area of land adjacent to a weir on the River Tweed, north of the B6350 road, due south of Coldstream and due south west of Cornhill on Tweed, from which one can reach the rest of Scotland directly only by crossing the weir.Wales:In Flintshire, on the Dee estuary, there are several bits of marshland that are separated from other bits of Wales.There is also a small area of land south of Wyastone Leys that is inaccessible from any other area of Wales directly by road, being separated by land and the River Wye.Several small uninhabited areas near the hamlet of Part-Y-Seal or Pant-Y-Seal near Grosmont, Monmouthshire are inaccessible from Wales directly; these include one farm, two river banks and a small island in the River Monnow. These appear to be due to shifts in the course of the river.In the United States of America:Shifts in the meandering course of the lower Mississippi River have created numerous pene-exclaves.Arkansas has territory at 35.65°N 89.87°W / 35.65; -89.87 across the Mississippi River on the northwest edge of Tennessee's Fort Pillow State Park, north of the Corona/Reverie, Tennessee irregularity (see below).Illinois' Kaskaskia, Missouri's Grand Tower Island and other Illinois and Missouri territory on each other's side of the Mississippi River.The state of Mississippi controls at least 11 exclaves on the west bank of the Mississippi River in Louisiana, while Louisiana owns 8 exclaves on Mississippi's side.Mississippi state also owns 14 exclaves on the bank in Arkansas, while Arkansas has 15 of its own on Mississippi's side.In California:Coast Guard Island in the Oakland estuary is part of the city of Alameda but is accessible only via a bridge from Oakland.The port community of San Pedro is part of the city of Los Angeles but is connected to the rest of the city only by a narrow strip of land known as the Harbor Gateway, four city blocks wide and several miles long.Santa Monica borders the Pacific Ocean on one side but it is otherwise completely surrounded by the City of Los Angeles.The City of San Diego has a significantly large exclave. It Includes the communities of San Ysidro, Otay Mesa, Palm, and other neighborhoods considered a part of San Diego. This piece of San Diego is separated from the main portion of San Diego by 7 miles, divided by the cities of National City and Chula Vista. Technically, it is connected to the rest of San Diego by a 7-mile, 2 inch wide strip of land below San Diego Bay. But it is essentially an exclave. It is commonly referred to as "South San Diego".The city of Coronado, nearly encircled by San Diego Bay, can be reached by land only via a narrow isthmus connected to Imperial Beach. A bridge also connects it to San Diego. Four other small pene-exclaves occupy the same peninsula. Coastal lands that are north of Wright Ave., at the northern end of First St., part of Coronado Ferry Landing Park and that surround most of Naval Air Station North Island (island before 1945) are part of the city of San Diego and are accessible on land only through the city of Coronado. A large portion of the famous Coronado beach is in the City of San Diego.Redwood Shores on the San Francisco Peninsula is part of Redwood City, California, but is only connected with the rest of the city by an area of wetland in San Francisco Bay. It is accessible only via the cities of San Carlos and Belmont.Devils Postpile National Monument in eastern Madera County, California, is inaccessible from the remainder of the county due to wilderness areas of the Sierra Nevada mountain range. It can be reached only via Mono County near Mammoth Lakes.General Grant Grove is an isolated, non-contiguous section of Kings Canyon National Park.Some privately owned land within Mariposa County is surrounded by Yosemite National Park in the area of Wawona, as it was grandfathered at the park's formation to remain private.Delaware – At least two parcels of land on the east (New Jersey) side of the Delaware River belong to the state of Delaware (the bulk of which is west of the river) and not to New Jersey. This is because within the "Twelve Mile Circle", the entire Delaware River, to the low water mark, is the territory of Delaware and not New Jersey (unlike many other river borders where the border is at some intermediate point in the river itself). As a result, certain areas (including the Killcohook National Wildlife Refuge and a portion of the Salem Nuclear Power Plant) on the New Jersey side of the river that have been expanded by adding fill into areas that were historically below the low water mark are considered part of New Castle County, Delaware, and not Salem County, New Jersey. Both of these areas are accessible by land only by traveling through New Jersey.Kentucky – Ellis Park Race Course, a Thoroughbred horse racing track in Henderson, Kentucky, actually lies to the north of the Ohio River that forms the border between Kentucky and Indiana. The border is based on the river's course when Kentucky achieved statehood in 1792; a change in course to the south left the land that would later house Ellis Park cut off from the rest of Kentucky by the river. A pair of bridges across the Ohio connect the track to the rest of Kentucky.Iowa – The town of Carter Lake, Iowa, occupied a meander on the left bank of the Missouri River, until 1877 when flooding caused the river to jump its banks, shortening the main stream. The meander became an oxbow lake and Carter Lake now found itself on the right bank, attached to Nebraska. A lengthy court case ensued; the Supreme Court of the United States held that the sudden change in the river's course did not change the original boundary, and Carter Lake was still part of Iowa. (Nebraska v. Iowa, 143 U.S. 359 (1892)). The Court delayed a final decree to allow Nebraska and Iowa to reach an agreement consistent with its holding, which they did. (145 U.S. 519 (1892)). All roads into Carter Lake run through Omaha, Nebraska.For similar geographic reasons several portions of Nebraska lie east of the Missouri River, mainly due to flooding and changes in the river's path:DeSoto National Wildlife Refuge near Blair, which borders Iowa. A portion of Iowa is also on the Nebraska side in the same area.McKissick Island near Peru, which borders Missouri.A section of land that borders Iowa, Sloan.Onawa Materials Yard Wildlife Area and Middle Decatur Bend State Wildlife Management Area near Onawa, Iowa.Louisiana – The island of Grand Isle is part of Jefferson Parish but can be reached on land only via a bridge from Lafourche Parish.In Massachusetts:Humarock, legally part of Scituate, was separated from the rest of the town in the Blizzard of 1898, in which the mouth of the North River shifted. The village is only accessible via a bridge which connects it to Marshfield, but has a peninsular connection to the mainland to the south at the old mouth of the North River, now Rexhame Beach.Long Island, situated in Boston Harbor, is part of the City of Boston (Suffolk County) yet remains accessible by road only from Quincy (Norfolk County).The town of Sandwich is partially separated in its northern portion by the Cape Cod Canal and is only accessible by road through the neighboring town of Bourne.Michigan –The "Lost Peninsula" in Monroe County, Michigan, can only be reached via Toledo, Ohio. It is otherwise surrounded by Maumee Bay in Lake Erie. (Map)The Upper Peninsula is attached by land to Wisconsin. It is connected to the rest of Michigan via the 5 miles (8 km) Mackinac Bridge on I-75.Missouri – St. Joseph Rosecrans Memorial Airport is separated from St. Joseph and Buchanan County by the Missouri River; the airport lies on the west bank of the river, with the remainder of the city and county on the east bank. The only land access to the airport from Missouri is via Kansas Route 238 through Elwood.In New Jersey: In Ocean County, Long Beach Township is split into four parts, each with sea access.Elsewhere in Ocean County, Ortley Beach and some other small sections of Toms River, otherwise inland, are located on Barnegat Peninsula.In New York:The construction in 1895 of the Harlem River Ship Canal isolated Marble Hill, a small portion of the northern tip of Manhattan (New York County). Initially an island, it was later physically connected to the Bronx by the filling of Spuyten Duyvil Creek. It remains politically part of Manhattan, to which it is connected by the Broadway Bridge. Thus, it is part of the Borough of Manhattan and New York County, but not the island of Manhattan.Rockaway Peninsula, part of Queens, is connected to the rest of New York City only by two causeways across Jamaica Bay, or through Nassau County.Riker's Island, the jail complex of the City of New York, is considered to be in the borough of The Bronx, but is only accessible via the Riker's Island Bridge, which terminates in the Borough of Queens.Manhattan's borders often extend to the shorelines of the other boroughs so that, for example, certain piers extending from the Brooklyn waterfront are part of Manhattan but accessible only from Brooklyn. Manhattan (New York County) claims the entire East River bed.A 250-foot-wide (76 m) strip of the Bronx is separated from the rest of the borough by Pelham Bay Park as a result of a past error in drawing the border. The only residential street in this pene-exclave, Park Drive, is accessible by car only via the town of Pelham, in Westchester County.A small part of the city of Mount Vernon is cut off from the rest of the city by the Cross County Parkway. The three streets of Alta Drive, Alta Parkway and Labelle Road can only be accessed by car via the town of Eastchester.The geography of the Catskill Mountains in upstate New York creates pene-exclaves in two counties. Halcott, at the southwestern corner of Greene County, and Hardenburgh, at the western corner of Ulster County, have extensive borders with neighboring towns in their respective counties. But those are along mountain ridgelines directly crossed only by hiking trails, or (in Halcott's case) poor-quality unpaved roads, and vehicles traveling to those towns from the rest of the county must take roads through neighboring counties to do so.The town of Hardenbergh is also an exclave of itself. The only road directly connecting its southern half, along the upper Beaver Kill, and the northern half along Dry Brook, now runs through state-owned Forest Preserve lands and is closed to vehicle traffic. To get between those two halves, cars must travel through neighboring Delaware County.Both cities in Dutchess County are pene-enclaves on the Hudson River. Beacon is otherwise surrounded by the Town of Fishkill, and Poughkeepsie by the town of the same name. While A bridge connects the city of Poughkeepsie to neighboring Highland, in Ulster County, the only connection to Beacon that does not require going through Fishkill is a passenger-only ferry between the city and Newburgh, in Orange County.In North Carolina:Knotts Island in Currituck County is only accessible by road through Virginia Beach, Virginia via a narrow strip of land from the west. A 45-minute ferry connects the island to the rest of Currituck.On the north shore of Lake Gaston lie several small areas connected only by land to Virginia. Most of these have road and bridge connections to North Carolina, but one small area south of Joyceville, Virginia has road connections only to Virginia.In Pennsylvania, the westernmost section of the city of Allentown is a pene-en(ex)clave connected at a quadripoint with the rest of the city; it is surrounded by South Whitehall Township.Also in Pennsylvania, Pond Eddy, an unincorporated area along the Delaware River in Pike County's Shohola Township, is not connected by road to anywhere else in the town, county, or state. It can only be reached by driving to the Pond Eddy Bridge via roads in New York.In Rhode Island, the city of Warwick has an exclave called Potowomut separated from the main body of the city by Greenwich Bay on the north and the town of East Greenwich on the west.Elsewhere in Rhode Island, Newport County consists of three islands and one mainland portion, connected to Aquidneck, by a bridge.In Tennessee, over a period of about 24 hours on 7 March 1876, the Mississippi River abandoned its former channel that defined the Tennessee-Arkansas border, and established a new channel east of the town of Reverie, Tennessee. This places Reverie on the Arkansas side, while most of the area of Tipton County is located east of the Mississippi River, the Tennessee side. The direct distance between Reverie and the county seat, Covington, Tennessee, is only 18 miles (29 km), but the road trip to Covington requires the driver to cross the Mississippi River at Memphis, and is longer than 83 miles (134 km).In South Carolina, small parts of Horry County lie on the north shore of the Little River or the nearby Intracoastal Waterway and can only be reached by land connection from neighboring North Carolina. The land is unpopulated and no roads exist in the area.Grand Isle County, Vermont, in that state's northwest corner, consists of the Alburgh Tongue (see above) and several islands in Lake Champlain. It is only connected to the rest of the state via bridges.In Virginia:The Eastern Shore, comprising Accomack County and Northampton County, is located at the southern tip of the Delmarva Peninsula, conterminous only with Maryland on its north. It is connected to the rest of Virginia by the 23-mile-long (37 km) Chesapeake Bay Bridge-Tunnel.Several pieces of land along the shores of Kerr Lake and Lake Gaston can only be accessed by land from North Carolina. Some areas are undeveloped, but others, especially along the south shore of Kerr Lake, have state highways and settlement.The resort of Mont Du Lac, Wisconsin, and the area to its north are accessible only by a 0.8-mile (1.3 km) section of Minnesota State Highway 23 that runs through Douglas County, in Wisconsin's northwest corner. Several local dead-end roads run off it; there is no way to reach this part of the county or state by vehicle from anywhere else in Wisconsin.Washington, D.C. – Theodore Roosevelt Island in the Potomac River is part of Washington, D.C., but only accessible by a footbridge from Virginia. Although the Theodore Roosevelt Bridge from Washington to Virginia passes over the island, one cannot exit from the bridge onto the island.Divided islands
In Australia: Boundary Islet, historically known as North East Islet, is a Hogan Group islet of less than two hectares (4.9 acres) that straddles the border of the Australian states of Victoria and Tasmania. The islet is Tasmania's only land boundary, and at 85 metres (279 ft) long, it is the shortest land border between any Australian state or territory.In Canada:Killiniq Island is shared between Nunavut and the province of Newfoundland and Labrador.Nunavut and the Northwest Territories (NWT) share four islands that are split by the 110° W meridian: Borden Island, Mackenzie King Island, Melville Island and Victoria Island. Excluding lake crossings, Melville Island contains three separate land boundaries between Nunavut and NWT due to coastal undulation, while Victoria Island contains six such land boundaries (one of which is on a small island).In the People's Republic of China:Zhongshan Dao is divided between Guangdong Province and the Special Administrative Region and former Portuguese overseas province of Macau.Part of Hengqin Island in Zhuhai, Guangdong Province is leased to Macau until 2049 to house the new campus of the University of Macau. The university campus is sealed off from the rest of the island by a fence, and access to the area is provided by an underwater tunnel to Macau.In the United States, the City and County of San Francisco has four pene-enclaves on three islands in San Francisco Bay, which it shares with neighboring counties:On Alameda Island adjoining Alameda County, artificial fill on the border between the two counties to build the Naval Air Station Alameda (now decommissioned) created the pene-enclave. This small piece of open space can be reached on land only by passing through Oakland and Alameda.There are two small (5.37 acres) pieces of land on the eastern end of Angel Island (Quarry Point and the tip of Point Blunt) that belong to San Francisco. The rest (99.3%) of Angel Island lies in the town of Tiburon, which is in Marin County.San Francisco and Contra Costa County share Red Rock Island. A tripoint with Marin County may sometimes be exposed at low tide.Also in the United States,Rhode Island and Connecticut share Sandy Point Island in Little Narragansett Bay.New Jersey and New York share Shooter's Island, a bird sanctuary located in the south end of Newark Bay off the north shore of Staten Island. (The small portion in New Jersey is further divided between two counties.)Delaware and Maryland share Fenwick Island.Maryland and Virginia share Smith Island in Chesapeake Bay, as well as Assateague Island on the Atlantic coast.Virginia and North Carolina share Knotts Island, Mon Island and Simon Island, separated from the Atlantic by an intracoastal waterway.North Carolina and South Carolina share Bird Island on the Atlantic coast.Florida and Alabama share Perdido Key in the Gulf of Mexico.Alabama and Mississippi share South Rigolets Island in the Gulf of Mexico, as well as an unnamed coastal island at the mouth of Bayou Heron.Minnesota and Wisconsin share Interstate Island State Wildlife Management Area in Saint Louis Bay between Duluth, Minnesota, and Superior, Wisconsin.Michigan and Ohio share Turtle Island in Lake Erie.At the mouth of the Columbia River, Oregon and Washington share Sand Island Dike and Rice Island.Altona was a Danish exclave within Germany from 1640 to 1864.Bhutan – Tarchen, Cherkip Gompa, Dho, Dungmar, Gesur, Gezon, Itse Gompa, Khochar, Nyanri, Ringung, Sanmar and Zuthulphuk were exclaves of Bhutan within Tibet from the 1640s until 1959.Bophuthatswana was a bantustan or "black homeland" that was granted nominal independence by apartheid South Africa from 1977 until being re-absorbed in April 1994, but it remained unrecognized internationally. It consisted of a scattered patchwork of individual enclaves, six that were true enclaves within South Africa and two that bordered Botswana and South Africa.Cheikh Saïd is a rocky peninsula in present-day Yemen between the Gulf of Aden and the Red Sea. Although as late as 1970, the Petit Larousse described it as having been a "French colony from 1868 to 1936," France never claimed formal jurisdiction or sovereignty over it.within China –Forbidden City – The Xinhai Revolution led to the overthrow of the Qing dynasty and the establishment of the Republic of China (ROC) in 1912. In exchange for the abdication of the last Qing emperor Puyi, the Qing court and the ROC government signed an agreement for the favourable treatment of the abdicated emperor. Puyi was allowed to retain his title as emperor and was accorded the courtesies as a foreign monarch by the ROC government, and the imperial court remained at the Forbidden City. The Dragon Flag of the Qing Dynasty remained hoisted inside the Forbidden City, certain government organs such as the Imperial Household Department, Imperial Clan Court and Ministry of Justice continued to exist within the palace walls, and the emperor continued to hold court, appoint officials and grant titles of nobility. Following the Beijing coup in 1924, the warlord Feng Yuxiang unilaterally revised the agreement, abolishing Puyi's title of emperor, his right to live in the Forbidden City and other related arrangements.Unlike Hong Kong Island, the Kowloon Peninsula and the New Territories that were added later constituted a pene-exclave of the United Kingdom from 1860/1898 until 1997. Kowloon south of Boundary Street was ceded in perpetuity, whereas the New Territories was turned over under a 99-year lease.Kowloon Walled City was a counter-enclave belonging to China on the Kowloon Peninsula of Hong Kong from 1898 to 1993. The question of jurisdiction led to a hands-off approach by Chinese and British authorities over the years until the quality of life became intolerable. A mutual decision to demolish the 2.6 hectares of structures was announced in 1987 and completed in 1994.Kwang-Chou-Wan was a pene-exclave of France on the south coast of China from 1898, upon its lease to France by Qing China, until its return by France in 1946; its territory included the islands in the bay and land on both banks of the Maxie River, covering 1300 km² of land.Kwantung was a pene-exclave of Russia and later Japan in the southern part of the Liaodong Peninsula in Manchuria that existed from 1898 to 1945 and included the ports of Port Arthur (or Ryojun) and Dal'niy (or Dairen), the latter founded in 1899. It was leased to Russia from 1898 until 1905, when Japan replaced Russia as leaseholder. After World War II, the Soviet Union occupied the territory in 1945, jointly administering it with the Chinese before turning it over to the People's Republic of China in 1955.Jinzhou walled central city remained an enclave of Chinese territory within Kwantung under the lease with Russia. This provision was substantially ignored by Japan after it replaced Russia.Macao was a pene-exclave of Portugal on the coast of the South China Sea from 1557 until 1999.Zhongshan Dao island in the Pearl River Delta was divided between China and Macao as a pair of pene-exclaves dating from ratification of the Treaty of Tientsin in 1862 through the 1999 return of Macao to China.Qingdao, with an area of 552 km², was a pene-exclave of Germany (also known as the Kiautschou Bay concession), and later Japan, from 1898 to 1922, adjacent to Jiaozhou Bay on the southern coast of the Shandong Peninsula in East China. The village of Qingdao became the German colony of Tsingtau. In 1914, with the outbreak of World War I, the Republic of China canceled the lease with Germany. Japan then occupied the city and province until December 1922, when it reverted to Chinese rule.Shanghai was the location of British (from 1846) and American (from 1848) Concessions (later Shanghai International Settlement from 1863–1943) and the Shanghai French Concession from 1849–1946. Unlike the British sovereign colonies of Hong Kong Island and Wei-hai-wei, these foreign concessions always remained Chinese sovereign territory.Wei-hai-wei was a pene-exclave of the United Kingdom that bordered the Yellow Sea in eastern Shandong province of China. The city was a British colony, known also as the Weihai Garrison and sometimes as Port Edward, from 1898 to 1 October 1930, when it was returned to China. Its current name is Weihai.Wei-hai-wei walled central city was excluded from the leased territory and remained an enclave of Chinese territory within Wei-hai-wei.Comtat Venaissin was an exclave of Papal territory within France from 1348–1791. It contained an enclave of another Papal territory, the city of Avignon and had a small exclave around the nearby town of Valréas.Despotate of the Morea on the Peloponnesos peninsula of present-day Greece was a geographically detached province of the Byzantine Empire from 1349–1460; during much of that time, in addition to the Mediterranean Sea, it was surrounded by "states under Latin rule."East Pakistan (1947–1971), now Bangladesh, was a pene-exclave of Pakistan (if one considers West Pakistan, site of the capital, Islamabad, as the main land) that bordered the Bay of Bengal, India and Burma. East Pakistan, with a distance of 1600 km separating it from West Pakistan, accounted for 70% of the country's exports and was more populous than West Pakistan.Fort of São João Baptista de Ajudá was a Portuguese exclave (initially around 1 km² in area and reduced to only 2 ha by 1961) within Dahomey/Benin from 1680 until 1961 (de facto annexation by Dahomey) or 1975 (Portuguese recognition).France – The island of Mont-Saint-Michel at the mouth of the Couesnon River prior to 1879 was a pene-exclave of Normandy, but only during low tide, when it was connected by a tidal causeway to the neighbouring coast. The raised causeway that was then built was replaced with a light bridge opened in 2014, thus making Mont-Saint-Michel an island again.Germany –East Prussia (1919–1939), a German pene-exclave during the Weimar Republic, was separated from Germany after World War I, when Poland regained access to the Baltic Sea (Polish corridor). The territory of East Prussia (essentially the old Duchy of Prussia) is now divided into Kaliningrad Oblast in Russia, the Warmian-Masurian Voivodship in Poland, and Klaipėda County in Lithuania.Hemmeres, (1922–1949), surrounded by Belgian territory, was the sixth and southernmost of the Vennbahn enclaves created in 1922; it contained five households. The railway suffered severe damage during World War II and was not rebuilt. It ceased being an enclave when Belgium annexed the entirety in 1949. Hemmeres was reintegrated into West Germany on 28 August 1958, by an agreement with Belgium.Jestetten is a German town in the district of Waldshut in Baden-Württemberg that was inaccessible except by traveling through Switzerland, until a connecting road was constructed.Roetgener Wald was two enclaves from 1949 to 1958. Unlike its present configuration, the German enclave in 1922 was smaller in area because the central portion (between Grenzweg and a boundary with three turning points west of the Schleebach stream) was Belgian territory. Because the road connecting the two outer German portions (Highways 258/399) was German territory until 1949, the German land formed one enclave. The intersecting north-south road from Fringshaus to Konzen (now Highway B258, which has no connection to the Belgian road network) was also part of the oddly shaped enclave. In 1949 Belgium annexed these roads, thus separating the enclave into two enclaves for the next nine years. In 1958 Belgium ceded the center section of territory to West Germany, in addition to returning the adjacent east-west connecting road. This created one larger enclave in its present form. Highway B258 is the only portion of land that, once having been a part of the Roetgener Wald enclave, is now not within the enclave.Belgium had a counter-enclave located near Fringshaus from 6 November 1922 until 23 April 1949, while Germany owned the connecting roads that were part of the Roetgener Wald enclave. These roads met at a traffic island north of Fringshaus, with the 2279 m2 island itself being a part of Belgium. This counter-enclave was extinguished in 1949 when Belgium annexed the German roads that intersected at the traffic island. In 1958, when Belgium returned the east-west road to Germany, this traffic island also became part of the Roetgener Wald enclave.Verenahof was a German exclave within Switzerland until 1967, at which time its border became attached to Germany through a treaty implementing a land swap of a total of just under 1.06 km² in equal shares.West Berlin, upon the division of Berlin after World War II and before the reunification of Germany in 1990, was de facto a West German exclave within East Germany. Twelve small West Berlin land areas, such as Steinstücken, were in turn separated from the main body of West Berlin, some by only a few meters. In addition, there were several small areas of East Berlin that were surrounded by West Berlin. All of Berlin was ruled "de jure" by the four Allied powers; this meant that West Berlin could not send voting members to the German Parliament and that its citizens were exempt from conscription.West Berlin exclaves:
Böttcherberg (N) (1949–1971) to East GermanyBöttcherberg (SE) (1949–1971) to East GermanyBöttcherberg (SW) (1949–1971) to East GermanyErlengrund (1949–1988) land connection to West Berlin establishedFalkenhagener Wiese (1949–1971) to East GermanyFichtewiese (1949–1988) land connection to West Berlin establishedFinkenkrug (1949–1971) inhabited, to East GermanyGroße Kuhlake (1949–1971) to East GermanyLaßzins-Wiesen (1949–1988) to East GermanyNuthewiesen (1949–1971) to East GermanySteinstücken (1949–1971) inhabited, land connection to West Berlin establishedWüste Mark (1949–1988) to East GermanyEast Berlin exclaves:
Eiskeller (E) (1949–1990) dis-enclaved at re-unificationEiskeller (N) (1949–1990) dis-enclaved at re-unificationEiskeller (S) (1949–1990) dis-enclaved at re-unificationWest-Staaken – de jure part of Soviet sector but de facto administered by Spandau Borough in the British sector; seized by East Germany in 1951 and made an exclave of East Berlin's Borough of Mitte, which it remained officially until being incorporated in 1961 by the neighboring town of Falkensee in non-Berlin East Germany.Gwadar was an Omani pene-exclave on the Arabian Sea coast of present-day Pakistan from 1784 until 1958.Ifni was a pene-exclave of Spain on the Atlantic coast of Morocco from 1859 to 1969.within India –Dadra and Nagar Haveli were enclaves inland from the Arabian Sea coast covering an area of 487 km². After invasion by pro-Indian Union forces in 1954, they achieved de facto independence from Portugal. They and three Portuguese pene-exclaves, the city of Goa and the two small coastal exclaves of Daman and Diu, were the last remnants of Portuguese India, which existed from 1505 until military conquest by India on 19 December 1961. (A 1956 map also shows a counter-enclave within Nagar Haveli belonging to Bombay.)French India – Pondicherry and the other exclaves of Karaikal, Mahé and Yanaon were absorbed into India de facto in 1954 and de jure in 1962 after the Algerian War. In 1761 the British captured all of them from the French (and also Chandannagar), but the Treaty of Paris (1763) returned them to France. Those possessions passed again to British control before finally being handed over to the French in 1816/1817 under the 1814 Treaty of Paris. Pondicherry, Karaikal, Mahé and Yanaon came to be administered as the Union Territory of Puducherry in 1963. All four are now sub-national ex(en)claves within India.Pondicherry, was the site of a trading center set up by the French East India Company in 1674, which eventually became the chief French settlement in India, after passing several times between Dutch, British and French control. It comprised 12 non-contiguous parts: three pene-exclaves on the Bay of Bengal and nine nearby true enclaves. Inside the main Pondicherry exclave was a small counter-enclave belonging to India straddling the Chunnambar River.Mahé (or Mayyazhi), a small (9 km²) town, was a pene-exclave on the Malabar Coast of the Arabian Sea from 1721. Mahé was composed of three non-contiguous parts, including Mahé town and two true enclaves: Cherukallayi and one consisting of Palloor, Chalakkara and Pandakkal.Yanaon (or Yanam), a 30 km² pene-exclave in the delta of Godavari River, nine kilometers from the Coromandel Coast and Bay of Bengal. It was a Dutch colony before France overtook it in 1723 and made it a French colony.Karaikal was a small coastal pene-exclave on the Bay of Bengal acquired by France in 1739 from the regime of Raja Pratap Singh of Tanjore. By 1760 it included 81 villages around Karaikal town.Chandannagar was a small true enclave established as a French colony in 1673, located on the right bank of the Hooghly River 30 kilometers north of Kolkata. Bengal was then a province of the Mughal Empire. The British returned the city to France in 1816, along with a 7.8 km² nearby enclave. In May 1950, with French approval, India assumed de facto control, with the de jure transfer in June 1952. In 1955 it was integrated into West Bengal state.Trincomalee was in present-day Sri Lanka (then a part of India) located on the Indian Ocean east coast of the island. By September 1782 it was occupied by the French after the Battle of Trincomalee with the British, only to be ceded back to the British in 1783.The Lado Enclave was a 39,000 km² exclave of the Congo Free State and later of Belgian Congo that existed from 1894 until 1910, situated on the west bank of the Upper Nile in present-day South Sudan and northwest Uganda.Mount Scopus (in Jerusalem) was an Israeli exclave in Jordan between 1948 and 1967, before being reunited with West Jerusalem following the Six Day War. Similarly, Ein Gev, located on the eastern shore of the Sea of Galilee, was a pene-exclave in Syria until Israel took over the Golan Heights territory, again during the Six Day War.Panama –Colón, an exclave of Panama from 1903 to July 27, 1939, was surrounded by the U.S. Panama Canal Zone, until a treaty provision connected it to the main part of Panama via a corridor.Panama City and the tip of Paitilla Point from 1903 to February 11, 1915, were pene-enclaves surrounded by the U.S. Panama Canal Zone and the Pacific Ocean. Maps of the Canal Zone dated before 1923 clearly show these borders. Maps dated 1924 and later show a changed border that re-connected Panama City with eastern Panama.When Madden Road was ceded to the U.S. by treaty on July 27, 1939, a Vennbahn-type Panamanian enclave was created that was bounded by Madden Road, the main Canal Zone boundary, and a contour line above Rio Chagres and Rio Chilibre. Another treaty that took effect on April 11, 1955, de-enclaved it.Panama had a water enclave in Limon Bay from 1979 to December 31, 1999. It also had jurisdiction over one building within the U.S. Summit Naval Station from October 1991 until the transfer of the station to Panama on December 31, 1999.Pogiriai (Pogiry) was a Lithuanian exclave of 1.7 km² that was ceded to Belarus in 1996.The southern section of the Emirate of Ras al-Khaimah was a national-level exclave surrounded by other emirates of the UAE and Oman for three months after UAE independence in 1971 until it joined the UAE in 1972.Between 1991 and 2003, Russia had three tiny pene-exclaves on tips of the lakeshore that bordered the Lithuanian side of Lake Vištytis. Before a new border treaty went into force on 12 August 2003, the border ran along most of the waterline of the beaches on the Lithuanian side, so anyone paddling in the water was technically crossing into Russia.Saint Pierre and Miquelon, a French territorial collectivity, was completely surrounded by the territorial waters of Canada from 1763 until 1992, when an EEZ corridor 10.5 NM (19.4 km) wide was created, stretching 200 NM (370 km) south to open sea.Schirgiswalde – In accordance with terms of the 1635 Peace Treaty of Prague, Austria transferred land (Ober- and Niederlausitz) to Saxony. However, because of religious affiliation with Austria, Schirgiswalde and five other towns (Güntersdorf, Gerlachsheim, Winkel, Taubentränke and Neuleutersdorf) within the transferred land remained with Austria, becoming Austrian enclaves within Saxony. 174 years later, to address problems as states began to consolidate, the 1809 Peace Treaty of Vienna mandated the transfer of these six enclaves from Austria to Saxony. However, the transfer did not occur until 1845 because of the need to correct mistakes in the names of the villages stated in the treaty and subsequent neglect. During that time, Schirgiswalde was de facto independent until economic reasons compelled the final transfer of the enclaves, thus extinguishing them.Sikkim – Dopta and Chumbi were exclaves of Sikkim within Tibet until China occupied them in 1958.Sweden – The Peace of Westphalia in 1648 granted certain possessions of the Holy Roman Empire to the Swedish Empire (extant 1611–1721) to be held as fiefs of the Holy Roman Empire:Bremen-Verden – states of the Holy Roman Empire bordering the North Sea; in "personal union with Sweden" until 1712, when they fell under Danish occupation in wartime.Swedish Pomerania – a state on the Baltic coast in present-day Germany and Poland; a small part was ceded to Prussia following war in 1720 and the entirety in 1815 during the Congress of Vienna.town of Wismar – town in northern Germany on the Baltic Sea; transferred to Germany in 1903 when Sweden renounced its claim.Syria was a pene-exclave of the United Arab Republic from 1958 to 1961 (if one considers Egypt as the UAR main land), bordering the Mediterranean Sea, Turkey, Iraq, Lebanon, Israel and Jordan.Transkei was a bantustan or "black homeland" that was granted nominal independence by apartheid South Africa from 1976 until being re-absorbed in April 1994, but it remained unrecognized internationally. It had two exclaves within South Africa that were true enclaves.Taebong and Goryeo - The southwest coast of South Jeolla Province in Korea was an exclave of Taebong or Goryeo, between 903 and 936.Turkey –The tomb of Suleyman Shah (b. ca. 1178–d. 1236) was located in or near Qal'at Ja'bar in modern-day Syria; in accordance with the 1921 Treaty of Ankara, the tomb "shall remain, with its appurtenances, the property of Turkey, who may appoint guardians for it and may hoist the Turkish flag there." The treaty is silent regarding sovereignty of the 6.3 hectares of land on which the tomb rests. The tomb was relocated in 1973 prior to the creation of Lake Assad.Ada Kaleh – Prior to the creation of modern Turkey, the Ottoman Empire held a small island in the Danube River surrounded by the waters of Romania, from at least the Berlin Treaty of 1878 until 1923 when, under the Treaty of Lausanne, Romania obtained sovereignty over it. It was submerged in 1970 by the construction of a hydroelectric plant, displacing up to 1000 residents.United Kingdom –Following the establishment of the Irish Free State, three deep water Treaty Ports at Berehaven, Queenstown (modern Cobh) and Lough Swilly were retained by the United Kingdom in accordance with the Anglo-Irish Treaty of 6 December 1921. As part of the settlement of the Anglo-Irish Trade War in the 1930s, the ports were transferred to Ireland (the Free State's successor) in 1938 following agreements reached between the British and Irish Governments.In 1625, King Charles I instituted the Order of the Baronets of Nova Scotia in an effort to colonize New Scotland, by offering the hereditary title, land ownership and power over new baronetcies in exchange for financing and materially supporting new settlements. Under Scots Law, Baronets "took seisin" by receiving symbolic "earth and stone" on the actual land, which was the feudal legal form of taking possession. However, to avoid a trans-Atlantic trip (and thus encourage applicants), the royal charter stated that "the realm of Nova Scotia, and original infeftment thereof, is holden of the kingdom of Scotland, and forms part of the County of Edinburgh." By royal decree, land in the courtyard at Edinburgh Castle was declared to be an integral part of Nova Scotia; thus, seisin at the castle was equivalent to seisin on the lands themselves. The ceremony of seisin was performed in the following years for 64 of the original Baronets. This decree has never been annulled, which fuels a belief that this enclave still exists as a tiny enclave of Canada within the grounds of the famous Scottish castle.United States –Horseshoe Reef (1850–1908) in Lake Erie consisted of underwater ledges of sunken rock near Buffalo, New York. Great Britain ceded a fraction of an acre of underwater land that was entirely surrounded by Canadian waters to the United States to construct a lighthouse. A 1908 treaty mandated a new survey in order to shift the boundary to include the reef in U.S. waters.The Captain Cook Monument at Kealakekua Bay and about 25 square feet (2.3 m2) of land around it in Hawaii, United States, the place where James Cook was killed in 1779, is owned by the United Kingdom. An historian on the occasion of the 50th anniversary recorded in 1928 that the white stone "obelisk monument [was] erected to the memory of Captain Cook, about 1876, and on land deeded outright to the British Government by Princess Likelike, sister of King Kalakaua, about the same year, so that that square is absolute British Territory." Hawaii was a sovereign nation at the time. According to a recent writer, "The land under the monument was deeded to the United Kingdom in 1877 and is considered as sovereign non-embassy land owned by the British Embassy in Washington DC. ... the Hawaiian State Parks agency maintained that as sovereign British territory it was the responsibility of the UK to maintain the site."Lake of the Woods – the American border with present-day Canada as defined under the 1783 Treaty of Paris and the Anglo-American Convention of 1818 inadvertently created two small maritime exclaves of the U.S. in Angle Inlet. The border depended on determining the northwesternmost point of the Lake of the Woods. Johann Tiarks' survey in 1825 placed its location at the edge of a pond on the Angle Inlet. (A 1940 academic study documented the location of Tiarks' point, which is in the immediate vicinity of 49°23′51.324″N 95°9′12.20783″W (NAD83).) In accordance with the 1818 treaty, the border ran south from this point to the 49th parallel. However, this line was "intersected at five points by the winding course of the boundary in the channel of the Northwest Angle Inlet; thus there were anomalously left two small areas of waters totaling two and a half acres belonging to the United States, yet entirely surrounded by Canadian waters." They were centered at 49°23′10.7514″N 95°09′10.8″W and 49°23′17.5914″N 95°09′11.6994″W. By treaty in 1925, the southernmost of these five intersecting points, 4785 ft. farther south than Tiarks' point, was adopted instead, which eliminated these exclaves.Panama Canal Zone, surrounded by Panama, the Caribbean Sea and the Pacific Ocean, was an American pene-exclave from 1903 to 1 October 1979, when the entity was extinguished by treaty with Panama. After that date, the former Canal Zone land remaining under U.S. sovereignty, greatly reduced in area, was a pene-exclave until 31 December 1999, when total transfer to Panama was complete.At El Cerro de Doscientos Pies ("200-Foot Hill"), 3.19 hectares of land in Panama near Las Minas Bay was annexed by the U.S. on 24 September 1928 and added to the Canal Zone. This true enclave apparently existed until 1 October 1979.On 1 October 1979, the day the Panama Canal Treaty of 1977 took effect, most of the land within the former Canal Zone transferred to Panama. However, the treaty set aside many Canal Zone areas and facilities for transfer during the following 20 years. The treaty specifically categorized areas and facilities by name as "Military Areas of Coordination", "Defense Sites" and "Areas Subject to Separate Bilateral Agreement". These were to be transferred by the U.S. to Panama during certain time windows or simply by the end of the 243-month treaty period. On 1 October 1979, among the many such parcels so designated in the treaty, 35 emerged as true enclaves (surrounded entirely by land solely under Panamanian jurisdiction). In later years as other areas were turned over to Panama, nine more true enclaves emerged. Of these 44 true enclaves, 14 were related to military logistics, 7 were military communications sites, 5 Federal Aviation Administration facilities, 5 military housing enclaves, 3 military base areas, 2 military research facilities, 2 parts of a bombing range, 4 secondary school parcels, 1 elementary school, and 1 hospital. At least 13 other parcels each were enclosed partly by land under the absolute jurisdiction of Panama and partly by an "Area of Civil Coordination" (housing), which under the treaty was subject to elements of both U.S. and Panamanian public law. In addition, the 1977 treaty designated numerous areas and individual facilities as "Canal Operating Areas" for joint U.S.-Panama ongoing operations by a commission. On the effective date of the treaty, many of these Canal Operating Areas, including Madden Dam, became newly surrounded by the territory of Panama. Just after noon local time on 31 December 1999, all former Canal Zone parcels of all types had come under the exclusive jurisdiction of Panama.The Val d'Aran is a valley in the Pyrenees mountains and a comarca in northwestern Catalonia, northern Spain. Most of it comprises the only part of Catalonia that is on the northern side of the Pyrenees. The Val d'Aran had been without direct access to the south side of the mountains, until the Vielha tunnel was opened in 1948.Venda was a bantustan or "black homeland" that was granted nominal independence by apartheid South Africa from 1979 until being re-absorbed in April 1994, but it remained unrecognized internationally. It was an enclave that was not an exclave, bordering only South Africa and separated narrowly from Zimbabwe by the Madimbo corridor to the north. Venda itself also had a small exclave that was a true enclave in South Africa.Walvis Bay was a South African pene-exclave bordered by the Atlantic Ocean and Namibia, before being incorporated with Namibia in 1994, four years after that country's independence.Zadar (Zara) was a 104 km² pene-exclave of Italy, bordering the Adriatic Sea and Croatia, from 1920 to 1944 (de facto due to abandonment by the Italian civilian administration) or 1947 (de jure under treaty).Various other historical foreign concessionsInnumerable medieval enclaves within EuropeAzerbaijan – The former Nagorno-Karabakh Autonomous Oblast was an enclave in Azerbaijan, but the internationally unrecognised Nagorno-Karabakh Republic is not, as it occupies territories bordering Armenia and Iran.United Kingdom –Cumbernauld and Kirkintilloch formed an exclave at county level, as a part of the Scottish county of Dunbartonshire sandwiched between Stirlingshire and Lanarkshire.

From Flintshire came the exclave of Maelor Rural District (bounded on three sides by England and on the west by the Welsh county of Denbighshire) and the enclave of the parish of Marford and Hoseley, surrounded and separated from Flintshire also by Denbighshire. They are now part of Wrexham.Domesday Hundreds of Cheshire map in 1086 displays an enclave of Hamestan surrounded entirely by Middlewich.The counties of Scotland before reorganisation in 1889 included dozens of exclaves.

In 1918 the post-monarchy duchy was split into two states, making Königsberg an exclave of the Free State of Saxe-Coburg. In 1920, the residents of that state voted to merge with the Free State of Bavaria, thus eliminating the three Bavarian enclaves.Schmalkalden/Suhl – Just after World War I, this Prussian enclave within Thuringia was divided between the two Prussian provinces of Saxony and Hesse-Nassau (thus it was a composite enclave). The two entities of Schmalkalden and Suhl separately were exclaves of their respective Prussian provinces.Innumerable medieval enclavesIn India, until 1952, France maintained Chandannagar, which reported to the Governor of Pondichéry, and which was an enclave in Bengal, just upriver from Calcutta.Korea –Siheung County, South Korea, was an enclave within Gyeonggi Province.

Dual nationality would have excluded her from the royal succession.In 1979, at Sender Zehlendorf, East Germany, an area of 300 metres in radius around a radio tower construction site was made an exclave of the Soviet Union. After a Soviet fighter plane had earlier collided with a radio transmission mast at the facility, causing it to collapse, the Soviet Union agreed to rebuild the mast. So that the stricter German safety regulations would not slow the construction progress, the area was declared a Soviet exclave for the duration of the work.Hans Island – Two pene-exclaves would be created by a land border between Canada and Denmark. Negotiations in 2012 between Canada and Denmark, not yet finalized, call for either a condominium or splitting the sovereignty over the disputed island. If the island were to be split by a boundary, it would create both Canada's and Denmark's second land border.Palanca Marshes – potential Vennbahn-type enclave of Moldova surrounded by Ukraine: Under a 2001 treaty between the two nations, Moldova is to transfer to Ukraine not only the asphalt (as it has already done), but also the real property under 7.7 kilometers of road (which is a portion of the 300 km road between Odessa and Reni), and to clarify the sovereignty of that land, which under that treaty is to be transferred to Ukraine.Croatian maritime exclave within Adriatic Sea waters of Italy and Slovenia – The Drnovšek-Račan agreement of 20 July 2001 defined the entire border between the countries, including the maritime border. According to this agreement, Croatia would get approximately one third of the Gulf of Piran and a maritime border with Italy, while Slovenia would get a corridor to international waters. This solution included a Croatian maritime exclave. However, such a solution could run afoul of the Convention on the Territorial Sea and Contiguous Zone, which prohibits sovereignty over parts of the sea unconnected to land. Article 4 states, "... the sea areas lying within the lines must be sufficiently closely linked to the land domain to be subject to the regime of internal waters," and "... baselines may not be applied by a State in such a manner as to cut off from the high seas the territorial sea of another State."
