Origin and history
The archaeological site of Crêt-de-Chatillon, located in Sévrier on the shores of Lake Annecy, is an emblematic example of the lakeside cities of the final Bronze Age (15th and 11th-9th centuries BC). These remains, including support piles and traces of wooden habitats, illustrate human occupation in a wetland, a major phenomenon of European prehistory. The excavations, initiated in 1856, discovered artifacts like a potter's oven, confirming the artisanal and domestic importance of the site.
This site is part of a wider set of lake towns studied in the Rhône-Alpes (now Auvergne-Rhône-Alpes), where the remains spread from Neolithic to Bronze Age. Archaeological surveys showed the richness of the perimeter, marked by a concentration of piles over 65 x 165 meters, classified as historical monument in 2011. The sub-lake island, partially explored, offers rare evidence of the construction techniques and lifestyle of prehistoric alpine communities.
The location of the site, off the banks of Sévrier, was specified by extended Lambert II coordinates, although its accuracy remains considered "passible" (note 5/10). The protected elements cover the entire submerged site, highlighting its scientific interest in understanding the dynamics of human settlement in wetlands at Bronze Age. No information is available on its current accessibility or on the services offered to the public.
