Roman aqueduct of Nîmes

The almost 50-kilometer-long aqueduct transported water from the springs near Uzès (Ucetia) to Nîmes (Nemausus). For a long time, it was believed that the aqueduct was built around 19 BC. However, recent archaeological findings suggest its construction in the middle of the 1st century AD. Upon its completion, approximately 20,000 cubic meters of water flowed daily to Nemausus, which had about 20,000 inhabitants at the time. Remarkable is the slight gradient of an average of 24 cm per kilometer over its entire length. About two-thirds of the pipeline ran underground, carved into the rock.
