Waldmannshausen Castle, Medieval castle in Elbtal, Germany.

Waldmannshausen is a three-story stone castle in Elbtal with round towers topped by cone-shaped roofs at two corners and a central staircase tower along its longer side. The entire property forms a larger complex that includes a connected building from 1790 and the original princely stables known as the Marstall.

The von Waldmannshausen family is first recorded in 1136; their seat was the Alte Burg north of the road to Frickhofen. Thebus von Waldmannshausen, a vassal of the counts of Nassau-Dillenburg, built the present New Castle from 1486 to 1488. In 1767 the ruined estate passed to Nassau-Oranien, then to Christian Heinrich von Erath, who had the castle repaired in 1786 and added a schloss in 1790. In 1935 the Schullandheim society of Hagen acquired it.

The name comes from the Walpode family of Waldmannshausen, first recorded in 1136, from whom the Waldbott von Bassenheim line branched off. Since 1935 the castle and the 1790 schloss have served as a Schullandheim, a country educational facility for school classes, owned by an association based in Hagen.

The castle sits roughly 18 kilometers north of Limburg an der Lahn and currently operates as an educational facility for groups and school classes. To visit, it is best to arrange a visit in advance since the site functions primarily as a reserved space for organized groups.

The Wirtschaftsgebäude opposite the castle, built around 1800, carries the inscription "UTILITATI.ET.OBLECTATIO" (to utility and pleasure) on its gable, with pilasters, a triglyph frieze and a triangular pediment emphasising its tall central section. Its sandstone well basin in the courtyard dates from the same period or slightly earlier.
