It was neighbored by the settlements Zürich–Enge Alpenquai and Grosser 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.
Once a former island or peninsula at the estuary of Zürichsee lakeshore and the Limmat, the settlement Kleiner Hafner represents all periods of pile dwelling.
[4] Already in the late 1860s, various prehistoric settlements were discovered in connection with the construction of the lake quai assets, and Groffried Keller pointed to a variety of dwelling posts.
Under the leadership of the former city archaeologist and pioneer of underwater archaeology, Dr. Ulrich Ruoff, the rediscovery of the prehistoric island settlement occurred on 24 December 1966.
The diet of the residents was surprisingly rich: wheat, barley, peas, poppy, wild apples, blackberries, raspberries, strawberries, hazelnuts and whitefish, perch, pike and catfish from the lake.
