Staufeneck Castle was built in the 12th century by Burggrafen von Staufeneck. In the year 1307 the castle went into the ownership of the Erzstift Salzburg, under whom it served as one of the maintenance courts in Rupertiwinkel from 1365 to 1805. In 1503, the castle was under Archbishop Leonhard von Keutschach who fundamentally transformed it, giving it its present appearance. Since 1894, the castle has been under private ownership. In the 20th ceuntry, the castle housed a museum. After a complete renovation, it is once again inhabited.
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.
