Aqueduct from Mons to Fréjus, Roman aqueduct in Fréjus, France.
The Aqueduct from Mons to Fréjus is a Roman water system that stretches roughly 26 kilometers from the hills of Mons to the coastal settlement. It overcomes elevation changes through buried sections, open trenches, and several stone bridges spanning valleys.
The aqueduct was built in the first century AD to supply the Roman settlement of Forum Julii with water. This was a major engineering feat that demonstrates how Romans managed water transportation over long distances.
The structure shows Roman craftsmanship through networks of buried channels, trenches, and bridges that cross multiple valleys.
Several preserved sections of the aqueduct are scattered throughout the area and can be viewed from outside, with the most accessible remains within Fréjus. Good walking shoes and extra time for exploring are helpful, since some sections lie away from main paths.
Water moved through the system slowly, taking about 17 hours to travel the entire route from start to finish. This gradual pace was actually intentional, helping prevent pressure buildup and damage to the structure.
