Hohenwang castle dates back to the 12th century and was one of the most important medieval fortifications that time. It is exceptional long structure and one the largest castles in Styria. It consists of the stronghold and two outworks, which are separated by trenches. Their massive decline began in the late 18th century, after it was severely damaged by an earthquake. During World War II more parts of the ruins were destroyed by bombing.
Hohenwang served as a local administrative center, the protection of the population in times of crisis, the case-colonization and the associated spread of Christianity in the upper Muerztal. From the 13th century a priest resided at the castle.
Hohenwang is an elongated complex with stronghold, a deeper front castle with gatehouses and a curtain wall. It is oriented from southwest to northeast and extends over a total length of 90 meters. A donjon was not available. From the 13th to the 17th century, the romanesque core eastward to the Palas, a gallery, a kennel, a bastion and a representative gatehouse was enlarged. In a 15th-century chronicle exists a more detailed description of the interior of the castle, in the place, inter alia, of the chapel, a servants' room, some room, a large hall, four cellar, four cereal boxes, a bath-room, a kitchen and vaulted stables for twelve horses is talk. The three well-secured gates, two of which provided with a slip gate, the attachment to the ditch and finally the south, west and north, very steep cliffs made a storming of the fortress to a difficult task. In addition to the engraving by Georg Matthäus Vischer, the castle is also shown on a proclamation image that had given Ulrich Christoph von Scherffenberg in 1631 in order.
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.
