The name Périgueux comes
from Petrocorii, a Latinization of Celtic words meaning "the four
tribes" – the Gallic people that held the area before the Roman conquest.
Périgueux was their capital city. In 200 BC, the Petrocorii came from the north
and settled at Périgueux and established an encampment at La Boissière. After
the Roman invasion, they left this post and established themselves on the plain
of L'Isle, and the town of Vesunna was created. This Roman city was eventually
embellished with amenities such as temples, baths, amphitheatres, and a forum
