Narbonne was established in Gaul in 118 BC, as Colonia Narbo Martius. It was located on the Via Domitia, the first Roman road in Gaul, built at the time of the foundation of the colony, and connecting Italy to Spain. Geographically, Narboanne was therefore located at a very important crossroads because it was situated where the Via Domitia connected to the Via Aquitania, which led toward the Atlantic through Toulouse and Bordeaux.
