History+
The castle's origins date back to the 14th century when it came into the possession of the noble Schönborn-Puchheim family. The current building is largely characterized by the 16th-century Renaissance, but architectural features from around 1460 are still discernible. During World War I, the castle was used as an internment camp for politically undesirable individuals. Subsequently, it served various purposes, including as a military and civil detention center, a federal educational institution, and a workhouse. A penal reform in 1974 ended the era of workhouses.
