Haus Klein-Schonebeck, Knight's seat in Appelhülsen, Nottuln, Germany

Haus Klein-Schonebeck is a rectangular brick manor house with stone detailing, standing in a pond that continues as a moat around the outer bailey. The present main house was built around 1520 and substantially rebuilt in 1587, when a stair tower was added. An 18th-century extension on the south side rests on pillars set into the pond.

Documented origins of Haus Klein-Schonebeck reach back to the late 14th century, when it was held by a branch of the Schonebeck family. In 1550 the estate passed to the von Brabeck family, followed by the lords of Aschebrock and von Westerholt. The present main house was built around 1520 and substantially rebuilt in 1587, when a stair tower was added.

The name Schonebeck refers to the noble family that lived here from the late 14th century; a branch at this house was hard to distinguish from the lines at Haus Groß-Schonebeck and Haus Nienberge. In 1550 the estate passed to the von Brabeck family, followed by the von Aschebrock and von Westerholt. The 1834 Urkataster records a moated field called Lusmannshof south of the house, suggesting two farms were absorbed into the estate.

The property remains privately owned and is not open to visitors, but the exterior can be viewed from the road that runs alongside it. The best vantage point offers a clear sight of the water-facing side and the connecting wooden bridge.

The stair tower added in 1587 is not described as octagonal in the sources, which record only that the house was extensively rebuilt that year and a Treppenturm was added. The moats around the site are now silted up, yet a second, already dry moat ring further south can still be traced in the terrain.
