Thomasberg Castle

In a document from Otakar IV, Otto de domesperg is mentioned in 1192. He was a ministerialis of the Styrian Ottokars. His fortified building was probably not located at the site of the present castle. The current complex dates from the mid-13th century. The families Torsäuler or von Ziegersberg are presumed to be the builders.

Towards the end of the 15th century, Thomasberg was owned by the Königsbergers. In 1503, Ehrenreich von Königsberg is named as the lord of the castle. He, and especially Wolf Matthäus von Königsberg, rebuilt and expanded the castle in the late Gothic style over the next decades. Through Ehrenreich Christoph von Königsberg, the dominion passed to Johann Quintin von Jörger in the first half of the 17th century.

In 1644, it came into the possession of Adam Graf Batthyány through a settlement, who transferred it to Karl von Pergen in 1653. The castle was hardly inhabited from the second half of the 17th century onwards. Karl II von Pergen had severely neglected Thomasberg. Although his son Joseph Anton had parts of the buildings re-roofed, this could not stop the long-term decay. Josef Freiherr von Dietrich, who had acquired the dominion in 1815, also had some maintenance work carried out. Under his son-in-law Prince Ludwig Sulkowsky, the castle continued to deteriorate.

After several owners, Thomasberg passed to the industrialist family Hamburger in 1902. The Prinzhorn family, still associated with Hamburger AG in Pitten, as well as the Lutz family, remain the lords of the castle today.
