Partly restored extensive castle complex situated on a hilltop, protruding over the Saar Valley. The complex, which consists of an outer bailey, a neck ditch and a central bastion, was built around 1350 at the order of Count Johann I of Lorraine. Renovation works have been undertaken since the 1960s, such as the restoration of a cellar vault under the central bastion. The castle walls and the remains of two preserved round towers are situated below the castle plateau. The Teufelsburg ("devil's castle") was conceived as a true battle castle and it was eventually destroyed during an armed conflict, the exact date of which remains unknown. The last documentary mention of the Teufelsburg dates back to the year 1699. There are still parts of the complex that have not yet been excavated. Also renovation works are still going on. The restored parts of the castle are all safely accessible to the public. They are being used for theatrical performances, renaissance fairs and medieval tournaments.
