Schloss Zinneberg, a local castle lying on the town's eastern outskirts on a prominent knoll on its namesake mountain, the Zinneberg, can nowadays only just be made out through the thick woods that have grown there. Its history most likely stretches back to the 11th century, although its origins are quite uncertain. Only in 1332, in a donation document to the noble family of Preysing, was the placename “Zinnenberg” reliably mentioned. As time passed, the castle found itself owned by several noble families who were influential in Bavaria.
