Narbonne

In Roman times, bustling, industrial Narbonne was the second-largest town in Gaul (after Lyon) and an important port, though today little remains of its Roman past, except an impressive underground warehouse (horreum in Latin) once used to store the wines and goods shipped in and out of the then bustling port (www.mairie-narbonne.fr). Until the sea receded during the Middle Ages, Narbonne prospered.
