Despite its middle-age style, the The Castle of Teleborg was built in 1900 by architect firm Lindvall & Boklund. The castle was built as a wedding present from count Fredrik Bonde af Björnö to his wife Anna Koskull. 17 years later the couple had died, and the castle was used as a hotel for young girls and for accommodation in general. In 1964 the city of Växjö bought it and the surrounding park from the Bonde family and is today mainly used for representation, weddings and conferences. Today, the castle is used by the city council for representational purposes, and the nearby university also uses some parts of the castle.
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.
