It dates from the Chalcolithic (or Copper Age), a period between 2700 and 2300 BC. During these four centuries, a brilliant culture flourished, known as the Fontbouisse culture, named after a site in the Sommières region (Gard) where similar remains were studied in the 1940s.
In the Garrigues (regions of limestone hills where garrigue grows) of the Gard, Hérault and Ardèche, the Fontbouisse people have built countless dolmens and villages with stone houses. There are over two hundred hamlets of this type, but barely 20% have been studied by archaeologists. There's still a lot of work to be done, and the Cambous site is just one example of the research being carried out in these regions.
