Wagner's Der Ring des Nibelungen (The Ring of the Nibelung), which is legendary for its length (15 hours over four epic operas), has Siegfried the dragonslayer as its main character. An obsession for many, this museum in the Altstadt lays out the stories and myths using family-friendly displays – kids can dress up as knights.
With reality lost in the mists of time, Wagner's tales of the House of Burgundy, and Norse settlers who settled in northern German from around the 6th century, include kings, rivalries, invasions and dragons.
