Where is this Mouse Tower?

The Mouse Tower (Mäuseturm) is a stone tower on a small island in the Rhine, outside Bingen am Rhein, Germany. The Romans were the first to build a structure on this site. It later became part of Franconia, and it fell and had to be rebuilt many times. Hatto II, the Archbishop of Mainz, restored the tower in 968. The story of how it came to be called the "Mouse Tower" comes from a folk tale.
