Grosser Hafner

Grossner Hafner 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.

Grosser Hafner was located on the then swamp area between the Limmat and Zürichsee around Sechseläutzenplatz on a small lake island in Zürich, and as well as the other Prehistoric pile dwellings around Zürichsee set on piles to protect against occasional flooding by the Linth and Jona. The settlement is located on Lake Zurich in Enge, a locality of the municipality of Zürich. It was neighbored by the settlements Zürich–Enge Alpenquai and Kleiner Hafner on a then island in the effluence of the Limmat, within an area of about 0.2 square kilometres (49.42 acres) in the city of Zürich. Grosser and Kleiner Hafner comprise 0.64 hectares (1.58 acres), and the buffer zone including the lake area comprises 16.56 hectares (40.92 acres) in all.

Internationally known is the area since 2009, as in the beginning of the construction of the underground parking facility at Sechseläutzenplatz the remains of Prehistoric pile dwellings around Zürichsee, in the immediate vicinity of the wetland soil settlement Kleiner Hafner in the lower basin of Lake Zurich, were found. Instead of a rescue excavation, the construction works were suspended for nine months and the settlement remains were systematically archaeologically recorded; the results of the excavations are permanently shown in the pavilion to the lakeshore.
