The devil once went to the Ahr valley and was so pleased with the land and its people, but especially the excellent red wine, that he forgot his way home. One day, while he was resting on the mountain opposite Are Castle, his grandmother approached him in the form of a beautiful girl. In the arms of the lovesick devil, she quickly changed back into the disgusting old woman he knew all too well. Angrily, he grabbed his grandmother and threw her back through the rock face into hell. This is how the Teufelsloch came into being, which can still be seen above Altenahr today.
