Roman aqueduct of Nîmes

In the Occitanie region, France, the Roman Aqueduct to Nîmes, whose most famous part is the Pont du Gard, once supplied the Roman city of Nemausus (today Nîmes) with fresh water.
History+
The almost 50-kilometer-long aqueduct served to transport water from the springs near Ucetia (Uzès) to the Roman city of Nemausus. While it was long believed to have been built around 19 BC, newer archaeological findings suggest its construction in the mid-1st century AD. After completion, approximately 20,000 cubic meters of water flowed daily to Nemausus, which at that time had about 20,000 inhabitants. The aqueduct crossed the Gardon river valley and ran about two-thirds underground, carved into the rock.
