Built in the 11th century, the main church of the Kyiv Pechersk Lavra monastery was destroyed during the World War II, a couple of months after the Nazi Germany troops occupied the city of Kyiv and the controversial 1941 Khreshchatyk explosions that destroyed the city's main street. According to the Soviet authorities, the church was destroyed by the advancing German troops, while at the same time German authorities put the blame on the withdrawing Soviet troops who practiced the tactics of scorched earth and blew up all the Kyiv bridges over Dnieper as well as being accused in the 1941 Khreshchatyk explosions.
In 1928, the monastery was converted into a museum park by the Soviet authorities and after its return no efforts were provided to restore the church. The temple was finally restored in 1995 after Ukraine obtained its independence and the construction was accomplished in two years. The new Dormition Church was consecrated in 2000.
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.
