"Gallic oppidum of the barred spur type, dominating the Ardèche. On the accessible side, it is defended by a monumental wall presenting three stages of construction. The first is represented by a rectilinear dry stone wall, pierced by a cart door which delimits a four-hectare oppidum, dated 130 AC Then, the enlargement of the oppidum results in a massive work punctuated by square towers involved in the work.
An external clavicula, usually found in Roman camps and serving as the forward defense of the gate, and the use of mortar to bind the core are seen in this second phase dating back to around 80 AC.
Finally, a third phase, around 50 AC, doubles this construction of overhanging towers, alternately round and square. This last state uses mortar more widely for facings and towers. At the rear of these fortifications is perceptible a habitat composed of houses of different sizes interspersed by a network of roads.
This site is undoubtedly the former administrative center of the city of the Helvians, before the creation of Alba Helviorum."
