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:
Ängsö Castle was first named as "Engsev" in a royal charter by king Canute I of Sweden (r. 1167-1196), in which he stated that he had inherited the property after his father Eric IX of Sweden. Until 1272, it was owned by the Riseberga Abbey, and then taken over by Gregers Birgersson.
From 1475 until 1710, it was owned by the Sparre family. The current castle was built as a fortress by riksråd Bengt Fadersson Sparre in the 1480s. In 1522, Ängsö Castle was taken after a siege by king Gustav Vasa, since its owner, Fadersson's son Knut Bengtsson, sided with Christian II of Denmark. However, in 1538 it was given by the king to Bengtsson's daughter Hillevi Knutsdotter, who was married to Arvid Trolle.
In 1710, the castle was taken over by Carl Piper and Christina Piper. Ängsö Castle was owned by the Piper family from 1710 until 1971, and is now owned by the Westmanna foundation. The castle building itself was made into a museum in 1959 and was made a listed building in 1965. It is currently opened to visitors during the summers.
The castle is a cubical building in four stores made by stone and bricks. The lower parts is preserved from the middle ages. It was redecorated and expanded in the 1630s. The 4th storey as well as the roof is from the expansion of Carl Hårleman from 1740-41. It gained its current appearance in the 1740s.
