Freienbach–Hurden Rosshorn is one of the 111 serial sites of the UNESCO World Heritage Site Prehistoric pile dwellings around the Alps, of which are 56 located in Switzerland.
The site is located on Zürichsee lakeshore in Hurden, a locality of the municipality of Freienbach in the Canton of Schwyz in Switzerland. Situated at the Seedamm, an isthmus between the Zürichsee and the Obersee lake area, it was in close vicinity to the prehistoric lake crossings, neighbored by three other Prehistoric pile dwelling settlements: Freienbach–Hurden Rosshorn, Freienbach–Hurden Seefeld, Rapperswil-Jona/Hombrechtikon–Feldbach and Rapperswil-Jona–Technikum. Because the lake has grown in size over time, the original piles are now around 4 metres (13 ft) to 7 metres (23 ft) under the water level of 406 metres (1,332 ft). The settlement comprises 4.32 hectares (10.67 acres), and the buffer zone including the lake area comprises 20.10 hectares (49.67 acres) in all.
Freienbach–Hurden Rosshorn provides early evidence of transport routes combined with special metal finds interpreted as sacrificial offerings. The site includes several lake crossings beginning in the Horgen culture. Several Early Bronze Age construction phases have been identified, as well as remains from the Hallstatt culture and Roman era providing dendrochronological dates about periods from which no other sites are known.
