After Hochosterwitz and Fortress Landskron, Glanegg is the third largest military complex in Carinthia. The history of the castle is first documented in 1121. The first owner was the Duke Henry III of Carinthia. After his death in 1122 it was inherited by his nephew, Count Bernhard von Marburg and later Otakar III. His son, Duke Ottokar IV left the castle after his death in 1192 to Leopold V. From 1473-1478 the castle was threatened by the Turks, but they failed to capture the castle. After three more owners, in 1534, King Ferdinand I owned the castle, but he had to sell it to Ulrich von Ernau because of his debts.
In 1818 by the castle was purchased by Hofrichter Hirzegger Ossiach, whose daughter, Josephine, married Klinze Glanegg, who was given the castle as a wedding present. In 1860 the castle was sold to Bregenz Mayor Ferdinand Kinz. After three more owners, the castle Glanegg finally came to a family of twins, which now own the castle.
The building is composed of various architectural elements, ranging from Romanticism to Renaissance. What is striking is the entrance to the round tower. The decay of the castle began in the mid-19th century.
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.
