Geyso-Schloss, Renaissance castle in Mansbach, Germany

Geyso-Schloss is a stone castle with multiple stories and a half-timbered section standing on high ground above the town of Mansbach. The structure shows building phases from different periods and operates today as both a residence and a museum open to visitors.

Wilhelm von Mansbach built the castle between 1577 and 1578 to replace an earlier fortress destroyed by Abbot Bertho IV of Fulda in 1276. This reconstruction represented the family's return to power and solidified their position in the region.

The half-timbered annex houses the Heimatmuseum, run by the Mansbach-Soislieden tourist association. The main building also serves as a venue for the non-profit Kulturverein Sonnenzeit, which aims to bring cultural life to Mansbach's village centre. From 2015 to 2017 the open-air Mansbach Music and Arts Festival took place here.

The main building remains privately owned and closed to visitors, but the museum section opens regularly for tours. It is best to check opening hours before your visit, as they may vary by season.

In 1944 Victor von Békésy, who had fled from the East, moved into part of the complex with a group of Huzul horses from his own breeding. The depot was directed by Karl Böhme, and on 13 May 1945 a division of the American cavalry occupied the castle.
