Stumo lock on the Nantes-Brest canal

Highlight • Other

The locks at this location with the keeper's house midstream were probably also serving as a mill to harness the water power from the main Blavet river channel.

Guernal lock on the Nantes-Brest canal

Highlight • Other

The Guernal lock is located in the town of Neulliac. It was built around the 1800s and is accompanied by several buildings (houses, stores, bridges over locks) whose restoration has not been completed.

Highlight • Bridge

Just before arriving in Pontivy the river Blavet crashes down a wide cascade, while the canal is channelled left through a lock. Pedestrians and bikers can cross the narrow metal walkway across the barrage and the locks to shortcut to the other side.

Château de Josselin seen from the Sainte-Croix bridge

Highlight • Castle

Erected at the beginning of the 11th century, the Château de Josselin was once just a simple wooden building. Rebuilt and extended over the centuries, it was modernized by the Rohan family who still live there today.

The castle can be visited and also houses a museum of dolls and toys.
