The Pont du Gard is an ancient Roman aqueduct bridge that crosses the Gard River in southern France.
It is part of a 50 km (31 mi) long aqueduct that runs between Uzès and Nîmes in the South of France. It was constructed by the Romans in the first century AD and was added to UNESCO's list of World Heritage Sites in 1985. It is the highest of all Roman aqueduct bridges, and has three rows of arches, standing 48.8 m (160 ft) high, and formerly carried an estimated 200 million litres (44 million gallons) of water a day to the fountains, baths and homes of the citizens of Nîmes.
