The Cistercian Abbey of Zbraslav was one of the most significant monasteries of the Cistercian Order in the Kingdom of Bohemia. Founded by King Wenceslaus II of Bohemia in 1292 it became the royal necropolis of the last members of the Přemyslid dynasty. The abbey was abolished by the Bohemian King and Holy Roman Emperor Joseph II in 1789. The best-known abbot of this monastery was Peter of Zittau († 1339) who wrote the Zbraslav Chronicle, the most important historical source for the history of Bohemia in the first half of the 14th century. The Zbraslav abbey is also known for the Madonna of Zbraslav, an outstanding Gothic painting from the 1340s.
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.
