This stunning sight-and-sound exhibition is dedicated to Das Nibelungenlied (Song of the Nieblungs), the epic German poem dating to around 1200. Cleverly installed in two medieval towers and the portion of the Old Town wall between them, the exhibition brings to life the saga of the dragon slayer Siegfried. The architecture of the structure itself is also fascinating, and the rampart provides a wonderful view of the town. The tour script (via headphones and printed matter) is offered in English. Allow 1½ hours for a thorough visit.
