History+
The origins of Rundeck Castle likely date back to the 12th century, when the first Erlingshofen Castle was built. In 1129, the Lords of Erlingshofen were first mentioned in documents. This family later moved to Arnsberg and then to Heideck, leaving the original castle abandoned and in disrepair. In 1381, Paul Stosser erected a new castle, named Stossenburg, on the foundations of the old complex. As early as 1383, Hans Stosser sold the castle to Duke Stephan the Kneißel of Bavaria-Ingolstadt. The castle changed hands multiple times, often as a pledged object. In 1409, the brothers Hans and Heinrich Absberger zu Rumburg acquired the castle. After Heinrich Absberger's death, his nephews sold the complex in 1481 to the Prince-Bishop Wilhelm von Reichenau of Eichstätt.
