Lorelei

The Lorelei (German: Loreley, German pronunciation: [loːʁəˈlaɪ]) is a rock on the eastern bank of the Rhine near St. Goarshausen, Germany, which soars some 120 metres above the waterline. It marks the narrowest part of the river between Switzerland and the North Sea, and is the most famous feature of the Rhine Gorge, a 65 km section of the river between Koblenz and Bingen that was added to the UNESCO World Heritage Sites in June 2002. A very strong current and rocks below the waterline have caused many boat accidents there.
