In the middle ages, Počitelj was the administrative centre and centre of governance of Dubrava župa (county), and its westernmost point, which gave it major strategic importance. It is supposed that the fortified town and its attendant settlements were built by Bosnia's King Stjepan Tvrtko I in 1383.
The walled town of Počitelj evolved over the period from the sixteenth to the eighteenth centuries. Architecturally, the surviving stone-built parts of the town are a fortified complex, in which two stages of evolution may be observed: mediaeval, and Ottoman.
It overlooks the town and represents the panoramic place.
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.
