Bingen is situated just southeast of the Rhine knee at the Bingen Forest (Binger Wald – actually a low mountain range), which rises west of the town. Rising to the north on the other side of the Rhine is the Rheingau range, the Taunus’s southwesternmost outcrop. In Bingen the river Nahe empties into the Rhine Gorge. Bingen forms the southern limit of the UNESCO Rhine Gorge World Heritage Site. The Rochusberg (mountain) is nearly completely surrounded by the town site.The settlement’s original name was Bingium, a Celtic word that may have meant “hole in the rock”, a description of the shoal behind the Mäuseturm, known as the Binger Loch. Bingen is well known for, among other things, the story about the Mouse Tower, in which allegedly the Bishop of Mainz Hatto was eaten by mice.
