Discover the largest multicoloured sandstone caves in Europe over twelve floors beneath the ruins of the ancient fortress.
Europe’s largest red sandstone caves with enormous domed halls and kilometre long passages on 12 levels, one above the other. The caves formed part of the Hohenburg castle, demolished in 1714, and were rediscovered in 1930. They were created by the removal of quartz for glass production and the provision of fire extinguishing sand.
A small museum displays interesting chapters from the caves’ history.
