Berwartstein Castle, near Erlenbach in the southern part of the Palatinate Forest, once belonged to the knight, Hans von Trotha, known in local legends as "Hans Trapp", and is the only castle in the Palatinate that is still occupied. The castle has been rebuilt and is open to visitors. Of many other castles, like Wegelnburg, only ruins are left. Other rock castles include Drachenfels near Busenberg, which partly belonged to rebel knight, Francis of Sickingen, Falkenburg and the Wilgartaburg near Wilgartswiesen.
