Samuel's Fortress in the old town of Ohrid was built during the rule of Tsar at the turn of the 11th century. Today, 18 towers and four gates still remain from the original structure. With its strategic location overlooking the town and the lake, it provides an ideal place for taking in the whole panorama of Ohrid and its surroundings. It was heavily restored in 2003 with the addition of entirely new battlements where none had survived.
According to recent excavations by Macedonian archaeologists, it was contended that this fortress was built on the place of an earlier fortification, dated to the 4th century BC, which was probably built by King Philip II of Macedon.
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.
