Amlishagen Castle was built in the 13th Century and first mentioned in 1253. In the second half of the 14th Century, 1601 and in the 19th Century the castle was expanded and renovated. The castle was owned by the Lords of Amlingshagen and later by the Lords of Wollmershausen. The castle is currently privately owned and occupied.
After the family von Wollmershausen died out in the 18th Century, the castle was owned by a number of individuals. The castle was finally bought by Gebhard Leberecht von Blücher the Prussian Generalfeldmarschall who led his army against Napoleon I at the Battle of the Nations at Leipzig in 1813 and at the Battle of Waterloo in 1815 with the Duke of Wellington. A distant descendant owns the castle today.
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.
