The Pskov Krom (or Pskov Kremlin) is an ancient citadel in Pskov. In the central part of the city, the Krom is located at the junction of the Velikaya River and smaller Pskova river. The citadel is of medieval origin, with the surrounding walls constructed starting in the late 1400s. The Krom was the administrative and spiritual centre of the Pskov Republic in the 15th century. In 2010, two of the towers of seven (the Vlasyevskaya, which dates to the 15th or 16th century, and the Rybnitskaya, which dates to 13th or 14th) were damaged in a fire.
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.
