Répudre Aqueduct, Stone navigable aqueduct in Paraza, France.

The Répudre Aqueduct is a stone waterway crossing over the Répudre River in Paraza and forms the passage for canal boats. The structure features a central arch and connects the water routes of the Canal du Midi system.

Pierre-Paul Riquet designed the aqueduct in 1675 to carry the Canal du Midi over the Répudre; Emmanuel d'Estan built it, and it was completed in 1676. Severe damage that winter forced a rebuild between 1676 and 1680. It is the oldest navigable canal aqueduct in the world and the only one originally built on the canal, with two others added by Vauban. It was listed as a monument historique in 1942 and repaired after a flood in December 1999.

A 19th-century plaque on the south face, placed by Pierre-Paul Riquet's descendants, names him as the engineer and Emmanuel de l'Estang as the architect. The bridge was repaired after a flood in December 1999 and listed as a monument historique in 1942.

The aqueduct lies between Paraza and Ventenac-en-Minervois and is easy to reach from the shore or Canal du Midi directly. Nearby you will find parking spots and access points to the canal for comfortable exploration.

Right after its first winter the stone structure showed such heavy damage that the entire build had to be replaced. This unexpected experience led to better construction methods for all following canal structures.
