A tour of France would be incomplete without this treasured region where Provence’s Roman past is preserved with the wildlife of the Camargue marsh Pont du Gard. This incredible aqueduct across a gorge in the Gardon River between Avignon and Nîmes is an engineering marvel you should not by-pass. Built by the Romans over 2000 years ago, it is a national site French school children visit on field trips from as far away as Paris.
