Origin and history
The archaeological site of Le Saut, located in Tresserve en Savoie, is immersed in Lake Bourget. It is one of the lake towns of the Auvergne-Rhône-Alpes region, showing a human occupation in a wetland during the age of the final bronze (XI-IXth centuries BC). The remains include wooden support piles, habitats and palisades, still visible today. These structures illustrate a way of life adapted to aquatic areas, characteristic of European prehistory.
Radiocarbon analyses revealed several phases of occupancy. A double picket palisade dates from -1310 to -1000 BC, corresponding to the average final alpine bronze. For the final Bronze phase 2b/3a, precise dates around -1073 to -1068 BC were obtained. The regular slaughter phases between -990 and -805 BC (Bronze final 3b) confirm a prolonged occupation, with abundant archaeological furniture. The date of -805 BC offers a key landmark for the extreme end of the final Bronze in the Alps.
Ranked Historic Monument by order of 24 October 2011, the site extends over a surface of 190 m x 75 m, marked by wooden piles. These exceptionally preserved remains make it a reference for the study of alpine lake habitats. The location, although partially approximate (level 5/10 precision), allows to study prehistoric human implantation dynamics in lake environment.
The site of Le Saut is distinguished by its size and state of conservation, offering a unique insight into the construction techniques and social organization of the bronze age communities. The piles, palisades and exposed furniture reveal an advanced mastery of piling architecture, adapted to environmental constraints. These elements make it a major heritage for understanding European protohistory.
