Graven House Castle history
The name of Graven House Castle is associated with the name of the squire Adolf Graven to whom the castle was transferred in 1341. The castle suffered great destruction during the Thirty Years' War and in 1656 the outer bailey of the castle was rebuilt, which is currently accessible. In 2020, the town of Langenfeld became the owner of the castle. The Foundation Stiftung Wasserburg Haus Graven gGmbH was created whose goal is to preserve the protection and make the historical castle complex permanently accessible to the public. The operator of the castle is Förderverein Wasserburg Haus Graven e.V..
