Schloss Willershausen, Medieval castle in Herleshausen, Germany.

Schloss Willershausen is a castle featuring a rounded shell corner tower and Gothic substructures located at Bergring 6 in Willershausen. The complex includes a half-timbered residential house that completes the estate layout.

A moated castle was built here in the mid-13th century; its builder is unknown, and the Treusch von Buttlar family is first documented as lords of Willershausen in 1383. Croatian cavalry plundered and largely destroyed village, church, estate and castle in 1634. After 1757 the estate passed by inheritance to the Landgraves of Hesse-Philippsthal-Barchfeld, who kept it until 1992.

The upper residential level from the late 17th century displays stucco work that shows how local craftspeople decorated homes for wealthy families during that period.

The castle is accessible from the southern part of the village and sits close to a fortified church. Walking through the area helps you see how the castle sits within the older village layout.

The round keep at the north end of the west wing has almost no windows and is capped by a conical roof; on nearly three sides it is still lapped by the Schlossteich, the remnant of the moat that once ringed the whole complex. The tower was renovated in 1731 for Hans Hermann Wilhelm Treusch von Buttlar, a major in the Saxon-Eisenach guard.
