[1][2] It is a small former island in the upper Lake Zürich in Rapperswil, a locality of the municipality of Rapperswil-Jona in the Canton of St. Gallen.

Multiple palisades and a clear visible settlement structure characterise the Early Bronze Age site dated in the 17th century BC.

[3] The finds include ceramic and dress pins, daggers, arrowheads, and fish hooks made of bronze, which were probably thrown as offerings into the lake.

The individual finds are varied, including pottery shards, an almost completely preserved decorated ceramic vessel, a stone and a bronze ax and a piece of a gold wire; a rare golden object yet discovered from the Bronze Age in Switzerland.

[4][5] As well as being part of the 56 Swiss sites of the UNESCO World Heritage Site Prehistoric pile dwellings around the Alps, the settlement is also listed in the Swiss inventory of cultural property of national and regional significance as a Class A object of national importance.
