The Schönfeld castle in the Saxon village of Schönfeld was first mentioned in the 13th century and expanded over the centuries. The aristocratic Schönfeld family sat here until the early 15th century. The buildings date from the years 1560 to 1580. In 1882, Baron von Burgk acquired the Schönfeld Palace and had it rebuilt by 1884. Today Schönfeld Palace is one of the most important neo-renaissance castles in Saxony.
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.
