Schloss Thurn (Ćiastel de Tor in Italian) is a three-storey residential tower which was built by the attendants of the bishops of Bressanone in 1230. It has first been documented in 1290. In this context the Lords of Rodank-Schöneck were feuds of the building until 1331. In the years to follow the residential tower was amplified by a crenelated circular wall and a great hall. Also the tower was modified and two storeys were added and converted into a granary. Also in 1500 there were renovations. The Roman great hall was enlarged and two round towers were added to the circular wall.
When the bishops lost reign of the Court of Thurn and the castle represented the centre of this complex, farmers purchased the castle. Until the castle has been rearranged it has been inhabited by their descendants.
Now Schloss Thurn is venue for the Ladin Museum. The exhibited items and documents provide an insight into the history, culture, legends and handicraft of the Ladin Dolomite valley. Moreover several events such as exhibitions and concerts take place in the inner courtyard.
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.
