Short description
This was the first pile dwelling site discovered in Lake Lucerne. Observations made in 2003 and 2004, as well as an underwater excavation mounted in 2008, showed that the site was used during four settlement phases in the Late Stone Age: during the Cortaillod and Pfyn Cultures, during the transition from Pfyn to Horgen, and during the Horgen Culture. The dendrochronological dates of the piles point to construction phases in the period between 3484 and 3431 BC, as well as around 3160 BC. The site is located on an approximately 60 m by 200 m terrace, which today lies 7 m under the surface of the lake, due to a later rise of the water level. The archaeological artifacts and sediments are extremely well preserved, thanks to the unusually big depth.

Neolithic

4300 – 3170 B.C.

Lake Lucerne

426 m.a.s.l.

Size of the site 1,26 ha / approx. 2 soccer pitches

Size of the bufferzone 5,14 ha / approx. 7 soccer pitches

Special features & highlights
The settlements once stood on a bank plateau that extended at least 60m into the lake. As the lake level rose over the millennia, the remains of the settlements gradually "disappeared" and are now five to nine meters below the lake surface.
