Which river does the Pont du Gard Roman aqueduct cross?

The Pont du Gard Roman aqueduct crosses the Gardon River in southern France. The monumental bridge stands near Vers-Pont-du-Gard and carried water toward the Roman colony of Nemausus, now Nîmes.

Built during the first century AD, the Pont du Gard formed one section of an aqueduct roughly 50 kilometres long. Roman engineers maintained a very shallow gradient so water could flow by gravity from springs near Uzès to the city. The bridge’s three tiers of arches rise about 49 metres above the river.

“Gard” and “Gardon” can create a naming trap. The river is commonly called the Gardon at the bridge, while hydrological naming conventions may call the combined downstream river the Gard after tributaries meet. For the Pont du Gard itself, Gardon is the standard quiz and heritage-site answer. The structure became a UNESCO World Heritage Site in 1985.
