The museum has a very complete exhibition area on the theme of prehistory. It illustrates the development of human settlements in the Diois. Indeed, since the Neolithic period, a population is settled in this territory. For starters they have no fixed houses, but a regional settlement.
The museum displays a menhir that dates back to 4500 BC and symbolizes this occupation. Is it a deity, a marker or a totem? We can’t know for sure. But the people who was settled down in the Diois found it relevant to mark physically their presence. The traces of this occupation are reinforced by the discovery of a “warehouse” cave, that was certainly used for storage rather than for living in. This cave was recreated in our museum. Towards the end of Neolithic, the “Sigottier” point, that we can only find in this area, emphasizes this territorial identity.
Later on, during the Bronze Age, the populations settle down in small villages traces of which can be found. Bronze items of Diois are part of an alpine culture of that times.
In the Iron Age the Gallic people of Vocontii occupies this region between the Rhône and the Alps. Hannibal passed through this territory, but what road did he take?
