Zürich–Enge Alpenquai is one of the 111 serial sites of the UNESCO World Heritage Site Prehistoric pile dwellings around the Alps, of which 56 are located in Switzerland.
Located on the then-swampland between Limmat and Lake Zurich around Sechseläutzenplatz on small islands and peninsulas in Zürich, the settlements were set on piles to protect against occasional flooding by the Linth and Jona Rivers. Because the lake has grown in size over time, most of 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), giving modern observers the false impression that they always had been underwater. Zürich–Enge Alpenquai is located on Lake Zurich lakeshore in Enge, a locality of the municipality of Zürich in the Canton of Zürich in Switzerland. The settlement comprises 2.93 hectares (7.24 acres), and the buffer zone, including the lake area, comprises 17.40 hectares (43.00 acres) in all. It was neighbored by the settlements at Kleiner Hafner and Grosser Hafner on a then peninsula respectively island in the effluence of the Limmat, within an area of about 0.2 square kilometres (49.42 acres) in the city of Zürich.
Alpenquai in the city of Zürich is one of the most important Late Bronze Age lakeside settlements in Central Europe; its huge size and its almost uninterrupted occupation from 1050 BC to 800 BC, rich imports, and the excellent state of preservation of the layers with unique organic finds and architectural elements, mark it as a cultural heritage site of worldwide importance. In addition, the final phase dates from the transition to the Iron Age, a period otherwise rarely found.
