Closed city

Structure and operations

Sometimes closed cities may only be represented on classified maps which are not available to the general public. In some cases there may be no road signs or directions to closed cities, and they are usually omitted from railroad time tables and bus routes.

Sometimes closed cities may be indicated obliquely as a nearby insignificant village, with the name of the stop serving the closed city made equivocal or misleading. For mail delivery, a closed city is usually named as the nearest large city and a special postcode e.g. Arzamas‑16, Chelyabinsk‑65. The actual settlement can be rather distant from its namesakes; for instance, Sarov, designated Arzamas-16, is in the federal republic of Mordovia, whereas Arzamas is in the Nizny Novgorod region (roughly 75 kilometres (47 mi) away). People not dwelling in a closed city were subject to document checks and security checkpoints, and explicit permission was required for them to visit. To relocate to the closed city, one would need security clearance by the KGB.

The closed city was sometimes guarded by a security perimeter with barbed wire and towers, much like a prison. The very fact of such a city's existence was often classified, and residents were expected not to divulge to outsiders their place of residence. This lack of freedom was often compensated by better housing conditions and a better choice of goods in retail trade than elsewhere in the country. Also, in the USSR, people working with classified information received a salary bonus.

Soviet Union closed cities

Closed cities were established in the Soviet Union from the late 1940s onwards under the euphemistic name of "post boxes", referring to the practice of addressing post to them via mail boxes in other cities. They fell into two distinct categories.

1. The first category comprised relatively small communities with sensitive military, industrial, or scientific facilities, such as arms plants or nuclear research sites. Examples are the modern towns of Ozyorsk (Chelyabinsk-65) with a plutonium production plant, and Sillamäe, the site of a uranium enrichment facility. Even Soviet citizens were not allowed access to these places without proper authorization. In addition to this, some bigger cities were closed for unauthorized access to foreigners, while they were freely accessible to Soviet citizens. These included cities like Perm, a center for Soviet tank production, and Vladivostok, the headquarters and primary base of the Soviet Pacific Fleet.
2. The second category consisted of border cities (and some whole border areas, such as the Kaliningrad Oblast, Saaremaa, and Hiiumaa) which were closed for security purposes. Comparable closed areas existed elsewhere in the Eastern bloc; a substantial area along the inner German border and the border between West Germany and Czechoslovakia was placed under similar restrictions (although by the 1970s foreigners could cross the latter by train). Citizens were required to have special permits to enter such areas.

The locations of the first category of the closed cities were chosen for their geographical characteristics. They were often established in remote places situated deep in the Urals and Siberia, out of reach of enemy bombers. They were built close to rivers and lakes which were used to provide the large amounts of water needed for heavy industry and nuclear technology. Existing civilian settlements in the vicinity were often used as sources of construction labour. Although the closure of cities originated as a strictly temporary measure which was to be normalized under more favorable conditions, in practice the closed cities took on a life of their own and became a notable institutional feature of the Soviet system.

Movement to and from closed areas was tightly controlled. Foreigners were prohibited from entering them and local citizens were under stringent restrictions. They had to have special permission to travel there or leave, and anyone seeking residency was required to undergo vetting by the NKVD and its successor agencies. Access to some closed cities was physically enforced by surrounding them with barbed wire fences monitored by armed guards.

The "box"

"Box" was the unofficial name of a secret Soviet facility much like the closed city, but smaller, usually the size of a factory. The "box" name was usually classified, as were the activities there. Incoming mail was addressed to "mailbox #XXXX", thus the name of "box". Most Soviet design bureaus for weapons, aircraft, space, military electronics, etc. were "boxes".

Russia

Russia has the largest number of closed cities. The policy of closing cities underwent major changes in the late 1980s and early 1990s. Some cities, such as Perm, were opened well before the fall of the Soviet Union; others, such as Kaliningrad and Vladivostok, remained closed until as late as 1992. The adoption of a new constitution for the Russian Federation in 1993 prompted significant reforms to the status of closed cities, which were renamed "closed administrative-territorial formations" (or ZATO, after the Russian acronym). Municipally all such entities have a status of urban okrugs, as mandated by the federal law.

There are currently 44 publicly acknowledged closed cities in Russia with a total population of about 1.5 million people. 75% are administered by the Russian Ministry of Defense, with the rest being administered by the Russian Federal Atomic Energy Agency, formerly the Ministry for Atomic Energy (Minatom). Another 15 or so closed cities are believed to exist, but their names and locations have not been publicly disclosed by the Russian government.

Some Russian closed cities are open for foreign investment, but foreigners may only enter with a permit. An example is the Nuclear Cities Initiative (NCI), a joint effort of the United States National Nuclear Security Administration and Minatom, which involves in part the cities of Sarov, Snezhinsk, and Zheleznogorsk.

The number of closed cities has been significantly reduced since the mid-1990s. However, on 30 October 2001, foreign travel (without any exceptions) was restricted in the northern cities of Norilsk, Talnakh, Kayerkan, Dudinka, and Igarka. Russian citizens visiting these cities are not required to have travel permits.

Krasnoyarsk-26 in Siberia, researched for the subject of Sidney Sheldon's 2001 fictional murder mystery-romance The Sky is Falling, was planned in 2003 to be shut down by 2011, in co-operation with the U.S, and documented by their Natural Resources Defense Council, but actually closed in 2008.

Travel restrictions

The following Russian localities do not have closed city status, but travel restrictions were imposed in November 2001 to all non-Russians, except for Belarusians.

Azerbaijan

Estonia

There were two closed cities in Estonia: Sillamäe and Paldiski. As with all the other industrial cities, the population of them was mainly Russian-speaking. Sillamäe was the site for a chemical factory that produced fuel rods and nuclear materials for the Soviet nuclear power plants and nuclear weapon facilities, while Paldiski was home to a Soviet Navy nuclear submarine training centre. Sillamäe was closed until Estonia regained its independence in 1991; Paldiski remained closed until 1994, when the last Russian warship left.

Tartu, home to Raadi Airfield, was partially closed. Foreign academics could visit the University of Tartu, but had to sleep elsewhere.

Moldova

Moldova has one official closed city – the commune Cobasna (Rîbnița District) in the disputed area of Transnistria. The commune, located on the left bank of the Dniester river, still contains military warehouses of the former Soviet 14th Army.

Ukraine

Ukraine had eighteen closed cities: among them the Crimean port of Sevastopol and the industrial city of Dnipropetrovsk, though both were restricted to foreigners, not locals. Travel restrictions were lifted in the mid-1990s.
