Château-Gontier Castle

Highlight • Monument

It is the castle that gave its name to the town. Only the fortifications remain. These ramparts are more than millennia old and were built in the 11th century.

Château Gontier

Highlight • Castle

Very pretty town with a market on Thursday mornings. Great place to stop for lunch or just to take a rest and look around the hilly side streets and expansive squares.

The Mirwault lock is the entrance for boaters to Château-Gontier. It is now mechanized and fully automated. The lock keeper is responsible and can take over if necessary. It's worth stopping by to see it in action.

Mayenne Viaduct

Highlight • Viewpoint

The Mayenne Viaduct is an impressive bridge that spans the Mayenne River for 300 meters and offers two ways to cross it: at road level with a bike or car, or at arch level with your feet. At the arch level, a wooden terrace located in the middle offers you a breathtaking view of the river and the surrounding landscape. You can also access the banks and towpath on both sides of the bridge, and enjoy nature and wildlife. The viaduct is part of the northern bypass of Château-Gontier, a charming town with a rich heritage that is worth visiting. Inaugurated in 2022, the viaduct is the largest road bridge in Mayenne.
