Stadtbredimus Castle has a history going back to the 13th century when a fortified castle stood on the site. In 1724, today's castle was built on the ruins of the old fort and, after some questionable restoration work, was bought by the la Fontaine family in 1802. Luxembourg's national poet, Edmond de la Fontaine, better known as Dicks, lived in the castle from 1858 to 1881.
The castle is now the headquarters of the Domaines Vinsmoselle wine cooperative.
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.
