An extensive labyrinth of underground passageways and cellar vaults has existed in the bedrock of castle hill for centuries - the Historic Rock-Cut Cellars. As early as 1380 red beer was stored in the subterranean cellars, sometimes comprising four levels, that had been cut into the Burgsandstein (local Nuremberg sandstone). During the air raids of World War II many citizens found shelter in these historical vaults. Reservations and Meeting Point: Brewery Shop Tours are offered in German and English.

The Musée Fin de Siècle Museum is a multidisciplinary museum dedicated to various art genres from the end of the 19th century.

The heart of the museum is an exhibition landscape on the history of the railway in Germany. The walking tour - over 2,500 sqm on two stories - covers two centuries, including all their technological and economic, political and cultural aspects.

Cenotes (sinkholes) are deep wells with crystal clear water that can be accessed when the roof of a cave collapses. Fed by underground rivers, the cenotes were the main source of freshwater for the Mayans and therefore are considered sacred. They are unique to the Yucatán peninsula, and still to this day, the underground cave system connecting all the cenotes remains largely unexplored. Witnessing the breathtaking beauty of the large clusters of stalactites and stalagmites being mirrored in the crystal clear cool waters is a unique experience. Every cenote has its own particular beauty, and putting on a swimsuit and snorkeling in the pool is an absolutely unforgettable experience. Some tour operators also offer cave diving excursions for very experienced divers.
