Palagruža

Name

The place is known in Italian as Pelagosa, derived from Greek pèlagos (πέλαγος, 'sea'). This is the source of the current Croatian name, as well as of the name of pelagosite. Gruž also means 'ballast' in Croatian, and the term is therefore well known in two ways to seafarers.

Legend and history

For some, Palagruža is associated with the Homeric hero Diomedes, king of Argos, who is reputed to be buried here, though it is hard to imagine where. Speculation is fuelled by the discovery of a painted 6th-century BC Greek potsherd with the name Diomed[es] on it (see image on Adriatica). A shrine of the cult of Diomedes here is perfectly thinkable. Authentic archaeological finds of the Neolithic, Greek, Roman, and early medieval periods have been recorded.

It is reliably recorded that the galley-fleet of Pope Alexander III landed here on 9 March 1177.

In the 15th and 16th centuries, there was a rise in fishing in the area, making the island the centre of a traditional fishing-ground of the community of Komiža, island of Vis, Croatia.

Palagruža is closer to Italy than to the Croatian mainland, being some 42 km (26 mi) from Monte Gargano. Before 1861, it belonged to the Kingdom of the Two Sicilies, and after 1861 therefore to Italy, but was unilaterally occupied by Austria-Hungary in 1873, without any declaration of war. The first action of the new authorities was to build the important lighthouse mentioned above, in 1875.

After Italy's entry into World War I, the country's armed forces occupied the island. The Italian Navy submarine Nereide was sunk there on the 5th of August 1915 by the Austro-Hungarian Navy's submarine U-5.

It reverted to Italy between the two World Wars, as part of the province of Zara (now Zadar, Croatia), and was ceded to Yugoslavia in 1947. Since the break-up of Yugoslavia, it has formed part of the sovereign country of Croatia.

Topography, economy and ecology

Vela Palagruža is some 1,400 metres (4,600 feet) long and 330 metres (1,080 feet) wide. The highest point of the archipelago, on Vela Palagruža (Italian: Pelagosa Grande), is about 90 metres (300 feet) above sea level, and on this elevation is a lighthouse. Palagruža is surrounded by dangerous waters, and landing can be difficult. It is uninhabited, except by lighthouse staff and by summer tourists who occupy two units of residential accommodation. There is one beach of golden sand. The lighthouse is also the site of a meteorological station. Other important islands in this archipelago are Mala Palagruža (Italian: Pelagosa Piccola), Galijula (Italian: Caiola) and Kamik od Tramuntane (Italian: Sasso di Tramontana)

Palagruža sits in the heart of fish-rich seas, including spawning grounds of sardines. It is a nature reserve, and the small amount of vegetation is of the Mediterranean type, for instance oleander (Nerium oleander) and tree spurge (Euphorbia dendroides). There are endemic plant species including a type of knapweed, Centaurea friderici Vis. (Palagruška zečina ). The algae, and their role in the production of the local mineral pelagosite, have been the subject of academic study (Montanari et al. 2007). The distinctive local fauna, including the black lizard now classed as Podarcis melisellenis ssp. fiumana and the related Podarcis sicula ssp. pelagosana (primorska gušterica in Croatian), was mentioned first by Babić and Rössler (1912).

Geology

Velika Palagruža is an apical part of subsurface geological complex, composed of carbonate, siliciclastic and evaporite rocks of different ages, ranging from Triassic (approx. 220 mil. years ago), through Miocene (approx. 10 mil. years ago), to Quaternary (recent deposition).

Climate

Palagruža has a weather station, established in 1894, which represents a major indicator of weather, especially wind, waves and precipitation on the open Adriatic. Weather conditions on the central Adriatic are dictated by movements of low-pressure area, which causes frequent changes of bora and scirocco winds. Annually, Palagruža Island has 104 days with strong (6-7 Bf), and 21 days with stormy winds (>8 Bf).

Due to its remote position in the middle of the sea, Palagruža exhibits more Mediterranean climate features than the Croatian coast. Summers are sunny and dry, while most of the rain falls in winter months. There are 2620 sunshine hours annually (1961–1990 average). Annual precipitation level of 304 mm (12.0 in) is the lowest of all Croatia. Maritime winds temper air temperatures compared with the mainland, with average summer daily highs of 26.5 °C (79.7 °F); on the other extreme, winter average daily lows are 8.4 °C (47.1 °F).

Flora and fauna

There are not very many types of creatures on this island but the ones that do live there are bright and colourful. Some snakes are poisonous but are mostly harmless.
