The property of the state, it has been listed since 1898 as a monument historique by the French Ministry of Culture.

The castle was built by the Hohenstein family and the Bishop of Strasbourg was one of the joint owners at the end of the 13th century. Bishop Berthold de Bucheck was imprisoned in the castle in 1337 by Rodolphe de Hohenstein. On his release, the bishop took the castle which did not recover from its ruin.
