Aqueduc de l'Yzeron, Roman aqueduct in Craponne, France.
The Yzeron aqueduct is a Roman water system with multiple collection branches that meet at specific locations in Grézieu-la-Varenne and Craponne. The structure spans a considerable distance and still displays visible pillars and water channels throughout its course.
Construction started in ancient times to supply water to the city of Lugdunum, now known as Lyon. This project represented part of Rome's effort to build major infrastructure across the region using advanced water engineering methods.
The remains show how Romans built water channels using clever engineering, with water flowing through multiple branches that people in the region still notice today. Walking along the structure, you can see how this system shaped settlement patterns in the area.
Visitors can follow a walking trail along the aqueduct's path to see different preserved sections of the structure. The best time to explore is during dry weather, as some areas have uneven ground and require careful footing.
The channel features a double siphon system at Le Tourillon, a rare Roman solution for managing elevation changes. This technical feature shows how ancient engineers solved difficult terrain challenges to keep water flowing forward.
