Gjirokastër Castle dominates the town and overlooks the strategically important route along the river valley. It is open to visitors and contains a military museum featuring captured artillery and memorabilia of the Communist resistance against German occupation, as well as a captured United States Air Force plane to commemorate the Communist regime's struggle against the 'imperialist' western powers.
The citadel has existed in various forms since before the 12th century. The first of the defenses were put in place by the Despots of Epirus, an off-shoot of the Byzantine government, who established the basic towered structure of the castle. Extensive renovations and a westward addition was added by Ali Pasha of Tepelene after 1812. The government of King Zog expanded the castle prison in 1932.
Today it possesses five towers and houses, the new Gjirokastër Museum, a clock tower, a church, a cistern, the stage of the National Folk Festival, and many other points of interest.
The castle's prison was used extensively by Zog's government and housed political prisoners during the Communist regime.
References:Towering 52 meters above the sea, Bengtskär lighthouse is the tallest one in Scandinavia. The building started in in 1905 after the shipwreck of S/S Helsingfors and was completed in 1906. The lighthouse was designed by architect Florentin Granholm. On December a special petrol lantern, designed and built in Paris, was brought to Bengtskär and installed atop the tower.
German fleet bombarded Bengstkär in the First World War in 1914. Since the Gulf of Finland was heavily mined, it was not until 1919 that the surrounding seas were declared safe for shipping, that the light was lit again.
After the war the military value of Bengtskär increased as part of the defence system of independent Finland. In Second World War (1941) Soviet Union made a suprise attack to island. After a bloody battle, the small Finnish garrison emerged victorious. Intermittent repairs to the facility continued during the post-war period.
