Weikersheim Castle (Schloss Weikersheim) is a castle in Weikersheim, Baden-Württemberg, Germany. It was built in the 12th century, but the exact year is not known. The castle was the traditional seat of the princely family Hohenlohe, and has been owned by the state of Baden-Württemberg since 1967 when the castle was bought from the estate of Prince Constantin von Hohenlohe, who had encouraged arts-related activities at the castle. Today the castle is home to the Jeunesses Musicales Germany during the summer and the controversial Weikersheim Think Tank, a conservative think tank. It is also used for large gatherings and weddings.
