Schloss Gutenberg stands on a prominent rock. IT was founded by Luitold III of Waldstein, who moved into the castle in 1185. The castle has belonged to the Stubenberg family since 1288. The oldest section from the 12th century was supplemented by a 2-story bailey that is protected by two moats. The outer moat is bridged today, the inner was filled in. The castle was remodeled and expanded, mixing the medieval style with Renaissance elements. An irregular four-story building complex with an almost pentagonal footprint and similarly pentagonal courtyard. The rustic gate faces south.
The southwest corner with the Chapel of Saint Pancras constitutes the oldest section of the castle. The chapel, originally constructed over three stories like a tower, with galleries in both upper stories, was dedicated in 1365. Entry is on the first gallery with frescoes that were isolated by the later addition of a dome. The frescoes from the second half of the 14th century show St. Alfa, St. James the Elder, the Martyrs of Ten Thousand, St. George, and the Caravan of the Three Kings. The Romanesque window behind the altar now has modern glass.
A chapel from about 1721 stands on the access road. The second chapel is from the third quarter of the 18th century. Two stone figures, St. Anna and St. John Nepomuk, originally from Schloss Wieden at Kapfenberg, also stand along the access road. Both are by Veit Königer, from about 1770.
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.
