This wall of coloured sandstone is part of the Drachenfels, a typical rock castle in the Pfalz in Germany, overlooking the upstream heights of the Rhine Plain. On the west part, the remains of a Roman fort were found. In later era’s it became a notorious haunt of robbers. The name of the rock is associated with the dragon from the Nibelungen Saga. Inside the rock are two cavities, which are called the 'dragon chamber' and the 'dragon cave' and indeed: the sandstone resembles the skin of a dragon.
