Douvenant Viaduct, Railway viaduct in Saint-Brieuc and Langueux, France.
Douvenant Viaduct is a brick railway structure connecting Saint-Brieuc and Langueux, built with a series of arches that create a striking profile across the landscape. The arches form a rhythm of solid supports that allow the line to traverse the terrain while supporting the weight of passing trains.
The structure was built in 1905 by engineer Louis Harel de la Noë as part of a railway network that expanded regional connections in Brittany. It represents an era when such engineering works were essential for linking towns and advancing transportation.
The structure has become a landmark that reflects how industrial engineering shaped regional identity in Brittany. Today, it serves as a gathering spot for walkers and cyclists who appreciate its role in connecting communities and preserving local heritage.
The best starting point is the Cesson cemetery parking area, where signs guide visitors toward the structure through walking paths. Multiple access points and viewpoints are available along the way, making it easy to explore the structure from different angles.
Visitors often overlook the curved design of this structure, which was engineered to follow the natural contours of the valley rather than cutting straight across. This thoughtful approach to construction made the viaduct blend with the landscape while solving complex terrain challenges.
