Hartheim Castle

The first mention of a Hartheim family, servants of the Bishop of Passau, dates back to 1130. In 1287, the brothers Konrad, Peter, and Heinrich von Hartheim exchanged the castle with Wilhering Abbey. Until the mid-14th century, the complex primarily consisted of a tower, possibly with an attached residential building, surrounded by a small wall with a rampart and moat. After several changes of ownership, the castle came into the possession of the Aspan family. This family initiated a new construction in the Renaissance style in the early 1590s, transforming the complex into a regular four-wing building with four polygonal corner towers and a taller central tower. In 1799, Georg Adam Prince Starhemberg acquired the castle. By 1862 at the latest, the building was in poor condition, as evidenced by a report from that period.
