Freienbach–Hurden Rosshorn — Wikipedia

Freienbach–Hurden Rosshorn, more often called Hurden Rosshorn or simply Rosshorn, is one of the 111 serial sites of the UNESCO World Heritage Prehistoric pile dwellings around the Alps, of which are 56 located in Switzerland. The Rosshorn site is exceptional because it doesn't contain remains of a prehistoric settlement but instead remains of prehistoric and historic bridges that were built in a shallow area of Lake Zurich.
