Roman aqueduct of Nîmes

The almost 50-kilometer long aqueduct was built to transport water from the springs near Uzès to the Roman city of Nîmes. While construction was previously dated to around 19 BC, newer archaeological findings suggest its creation in the mid-1st century AD. A key component was the bridge over the Gardon River valley, which enabled the transport of approximately 20,000 cubic meters of water daily to Nîmes, a city with about 20,000 inhabitants at the time. Approximately two-thirds of the pipeline ran underground, carved directly into the rock. The entire aqueduct exhibited a low gradient, averaging 24 cm per kilometer.
