Fréjus Roman Aqueduct

Description

The aqueduct of Fréjus was built in the middle of the first century after the ramparts were in place. It functioned for 450 years until the 5th century. It is 42 km long, with a difference in altitude between the highest spring of Neïssoun and the castellum aquae in the city of 481 m. The aqueduct runs mostly in a covered conduit for 36.4 km and for 1.8 km on bridges and 500 m on walls. Large parts of the aqueduct are still well preserved.
