After the Romans settled the area in 120 BC the hill was redeveloped, the residential areas were reorganised, and the road through the settlement from the east gate to the south gate was paved. The south gate was enlarged and a large square was cleared behind with a civil basilica, stones of which made their way in the second century AD to the staging post. The Via Domitia would have passed around the hill, but it has been speculated that it passed along this narrow road. The route of the Via often passes along roads with the name 'Route de la Monnaie', but as this originates from a translation of 'raised road' it merely shows that the road was using Roman construction techniques rather than that it formed part of the Via Domitia. The south gate does lead to a 'Route de la Monnaie', but the paved road in the oppidum has a gradient of 9% and is too narrow for carts to pass, although it would have been suitable for important visitors. The paved road at the east gate leads towards the bridge, but stops abruptly at a steep bank. It is thought that the river has undercut the bank at this point and removed all traces of the road.
