 To put an end to this, Bischof von Trier put the ring around the tower, and said that every captured robber would be then hanged from it to demonstrate to others what would become of those of this kind”.Another story claims that there was a huge flood and the ring marks the high-water mark, while another version asserts that Bischof von Trier once freed the tower's Lord from the flood.To thank him for this, the Lord fixed the ring to the tower as a symbol of the "Bischof's ring" and at the flood level of the Moselle.
