Weißenborn Castle was first mentioned in a document in 1213 together with the village of the same name. Weißenborn was given to the Freiberg family von Hartitzsch as a fief in 1365, and it remained in their possession until 1802. The castle was built probably in the 14th century. Weissenborn was also not spared from wars, looting and the plague.
In 1802, Alexander von Hartitzsch sold the castle and manor to Christoph Schubert, who passed both on to a cavalry master from Weißenbach . Colonel Freiherr von Wangenheim acquired the manor from Count Hohenthal-Püchau in 1882 and kept it until 1924. In 1931, Dr. Otto Fritz new owner of the manor and expropriated in 1945. During the GDR era there was a culture house in the premises. Weissenborn Castle has been privately owned again since 2010.
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.
