Pont du Gard
The Pont du Gard is a three-level stone aqueduct crossing the Gardon river valley, about 25 km west of Avignon. Built over 2000 years ago, in 19 BC, by Marcus Vipsanius Agrippa, the son-in-law of Augustus.
A road bridge was added to the structure in 1743 and used until 1996. The site is now well maintained and a very popular tourist attraction.
