Schloss Langenrain, Heritage manor house in Allensbach, Germany

Schloss Langenrain is a rectangular, two-storey baroque building under a steep tiled roof, its yellow walls set behind a broad gravel drive. The west side has a portal reached by an outdoor staircase, above which is the alliance coat of arms of Marx Anton von Ulm and Maria Franziska von Bodman. Inside, some rooms have stucco work, and the upper floor holds an 18th-century stove faced with multicoloured glazed tiles. A two-storey half-timbered barn with a hipped gable roof stands on the grounds.

The manor was built in 1686 by Marx Anton von Ulm to replace an earlier widow's estate on the site. It passed to the Bodman family through inheritance in 1814 and remained in their hands for generations.

Above the west portal, reached by an outdoor staircase, is the alliance coat of arms of Marx Anton von Ulm and his wife Maria Franziska von Bodman, carved when the house was built in 1684–1686. The paired shields record the marriage that joined the two families who owned Langenrain.

The property is accessible for visits and events, with historic rooms and outbuildings forming distinct areas of interest. Visitors should note that access and opening hours depend on the current use as a private residence.

From 1992 to 2006, the building served as a training facility for Konstanz University of Applied Sciences before returning to private use. This educational period left traces in the building's equipment that remain visible today.
