According to a saga Charlemagne has been sleeping in a cave of Mt. Untersberg since many centuries. His beard is growing longer and longer around a table and has grown round two times. The legend says, when the beard has grown three times around the table and when the ravens stop flying around the mountain, the end of the world has come. Then the Emperor will leave his cave and will fight the last great battle of humankind on the Walserfeld in the west of Salzburg.
