At 955m above sea level, Buffavento castle stands the highest of the three crusader castles in Cyprus. It probably originated as a Byzantine watch tower to guard against Arab raiders in the 10th century. The castle was extended during the Lusignan rule (1192–1489). The Lusignan kings used the castle mainly as a political prison. In particular, Peter I when reluctantly warned by his friend John Visconti of the queen's infidelity, repaid the favour by imprisoning and torturing him at Kyrenia, and later locking Visconti up at Buffavento to starve to death. By the 16th century, the castle was dismantled by the Venetians in an attempt to protect themselves, as their focus moved to the strongholds along the coast at Kyrenia and Famagusta.
From the seaward side, the castle is almost invisible, and the best long distance view is from the Nicosia side, where you can clearly see the remains of the castle bulging out from the top of the mountain. On the top level there are remains of a few buildings and a ruined chapel. However, the climb is worth it for the views alone, taking in Kyrenia, Famagusta, Nicosia and, on a good day, the Troodos Mountains.
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.
