In 1985, the Pont du Gard, one of the best preserved ancient Roman aqueducts, became a UNESCO World Heritage Site. It crosses the Gardon River near the town of Vers-Pont-du-Gard in the South of France, part of a 50 km (31 mile) system that brought water from a spring at Uzès to the Roman colony of Nemausus (Nîmes). Nîmes is approximately 23 km (14 miles) away.
As well as an aqueduct, it was also a toll bridge but only tourists cross it today. It was known as the highest of all elevated aqueducts.
