Roman City Vesunna

Vesunna, now known as Périgueux, was a Gallo-Roman settlement. Its remains offer a glimpse into ancient life in the Nouvelle-Aquitaine region of France.
History+
The origins of Vesunna date back to a Celtic settlement of the Petrocorii. After the Roman conquest of Gaul in 52 BC, this settlement was developed into a city. It is reported that Saint Fronto worked here as a missionary and bishop during Roman times. The city had an amphitheater with a capacity of 10,000 spectators and was entirely surrounded by a city wall. Remains of both structures are still preserved today, with the arena found within a park and parts of the city wall integrated into later buildings.
