Hermann's Cave, together with Baumann's Cave, is one of two show caves in the village of Rübeland near the town of Wernigerode, in the district of Harz, Saxony-Anhalt, Germany. The cave was formed out of the Devonian limestone of the Elbingerode complex during the shaping of the Bode Valley. It was discovered in 1866 during road works and was soon opened up to visitors. As a result of being protected early on its rich dripstone stalactites and stalagmites have been largely preserved.
