 Greng,  |   Spitz

Short Description
The tip of the Greng peninsula comprises four sites dating from the Middle Neolithic, Late Neolithic and Late Bronze Age. The latter, known since 1888, extends to the tip of the peninsula, on dry land and in the lake. It is subject to severe lake erosion following the lowering of the water level in the Three Lakes. The first surveys of the piles were carried out in 1921. Since then, it has been the subject of protective measures on the shore and topographical surveys in 2014 and 2015. The Middle Neolithic sites extend to the south and west, under the reed bed, and are also affected by erosion. As for the Late Neolithic occupation in the south-east, it was disturbed by dredging work carried out in 1865.

Special Features & Highlights
To the south-west of the site, submerged under two metres of water, are two circular mounds of pebbles and the piles of a fourth lake dwelling site, previously unknown. The function of the pebble circles, which are likely related to the nearby pile dwelling sites, is still unknown, but a parallel could be drawn with a series of more than a hundred circular pebble deposits recently discovered under the waters of the canton of Thurgau, on the south-western shore of Lake Constance, which may have been used for ritual purposes.
