Chronological conclusion

The presently available evidence leads to the following: the site dates from the final “La Tène” period when a shrine and perhaps an oppidum existed. It was occupied by the Romans at the time of the conquest by Julius Caesar, then reoccupied during the Augustan period, with important agricultural, industrial and commercial functions.

There was definitely a military presence and there is no doubt that it laid on a major strategic Roman road. At this time, the buildings would have been light constructions. The temples, theatre and baths were added progressively during the first and second centuries, on top of previous habitations. Aerial photography has shown up a road grid work.

At some later date, perhaps at the time of the barbarian invasions, the agglomeration may have been surrounded by a wall with towers, which would account for the legend of a city surrounded by a wall with towers.
