Damtschach Castle

History+
The origins of Damtschach Castle lie in a fortified farmstead that belonged to Aichelberg Castle. After Aichelberg was destroyed in the conflicts between Emperor Frederick III and King Matthias Corvinus, Emperor Maximilian I approved the expansion of the farmstead. Augustin Khevenhüller then built a manor, which was not inhabited by his family but managed by administrators. In 1629, the estate changed hands when Paul Freiherr von Khevenhüller sold it to Hans Sigmund Graf von Wagensperg. Through his granddaughter, it came into the possession of the Counts Galler, who transformed the castle into a Baroque ensemble from 1684 onwards.
