History+
The first documentary mention of Saldenheim dates back to 1193, followed by the naming of a Cholo von Saldenhofen in 1222. Later, the castle came into the possession of the Lords of Pettau, who sold it in 1348 to Otto von Liechtenstein and Murau. During the Hungarian War, the Liechtensteins supported the Hungarian forces, which led Emperor Frederick III to storm and destroy the castle. The Liechtensteins subsequently built the present castle. After the extinction of this family branch, it passed to the Windischgrätz, but fell into disrepair in the 18th century. After several changes of ownership at the beginning of the 19th century, Georg Kometer, Baron von Trübein, acquired the property in 1844 and had it rebuilt. The existing building fabric was restored, and romantic decorations were omitted to preserve the 17th-century appearance. The castle chapel dedicated to the Holy Trinity was built in 1668 by Johann Friedrich von Windischgraetz according to the building inscription and consecrated in 1670, presumably preceded by an older Gothic double chapel first mentioned in 1417.
