Krumbach Castle was constructed as a fortress in the 11th century. In 1192 Gerhardus de Chrumpach was mentioned in documents for the first time. The fortress was destroyed by the Magyars in 1260. It was later owned for over 200 years by the family of Pálffy von Erdöd.
Sold to an Austrian lawyer 1875, the castle changed private owners several times. It was converted into a hotel in 1993 and owned by the Austrian investor Mirko Kovats and his Artis Hotel Group as of 2009. Since 2020, it has operated as Schloss Krumbach International School, a private school with boarding.
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.
