The Rosshorn is the tip of the Hurden peninsula in the Swiss Canton of Schwyz that protrudes into Lake Zurich.

Prehistoric pile dwelling settlements were built at several sites in the vicinity, most notably Freienbach–Hurden Seefeld and, on the Rapperswil side, Rapperswil-Jona–Technikum as well as Rapperswil-Jona/Hombrechtikon–Feldbach.

Freienbach–Hurden Rosshorn provides early evidence of transport routes combined with special metal finds interpreted as sacrificial offerings.

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.

[1] As well as being part of the 56 Swiss sites of the UNESCO World Heritage Prehistoric pile dwellings around the Alps, the Rosshorn site is also listed in the Swiss inventory of cultural property of national and regional significance as a Class A object of national importance.
