Wiesberg Castle stands above the Trisanna River, where the Paznaun Valley leads into the Stanzer Valley. The castle was probably built in the 13th century. From the end of the 14th century until 1411, the castle was owned by the Rottenberger family. From 1770 until 1840, the castle was owned by the Dukes of Wolkenstein. Near the castle in 1809 several hundred local militia defended the area against Bavarian and French troops. Today Schloss Wiesberg is a privately held property and is not open to the public. The castle can be seen from the Silvretta-Hochalpenstraße.
References:The Gravensteen is a castle in Ghent originating from the Middle Ages. The name means 'castle of the counts' in Dutch. Arnulf I (918–965), Count of Flanders, was the first to fortify this place, building a medieval bastion on this high sand dune, naturally protected by the river Leie and its marshy banks. This bastion consisted of a central wooden building and several surrounding buildings, also in wood.
In the early 11th century, the wooden building was replaced by a stone residence, consisting of three large halls that made up three storeys, connected by a stone stairwell. The monumental stone staircase, the light openings, the fireplaces built into the walls and the latrines were signs of considerable luxury and comfort in those days. There was probably also a tower.
