Rocks of the Teutoburg forest in northwestern Germany, near the Osnabruck triangle, Munster and Bielefeld with magical and nationalistic value. It was probably a Teutonic religious place before Christian monks arrived after Charlemagne's conquest in the 8th century. The monks carved images into the rock bending the tree of Irminsul, the ash of life that brought together heaven and earth. Today it is a tourist spot near the statue of Arminio.
