Écluse du Moulin-du-Comte

The Écluse du Moulin-du-Comte is a lock on the Vilaine River in Rennes that controls water flow between two different elevations. The structure features the typical components of such works: gates, chambers, and walls that guide vessels through level changes.

The lock was built between 1822 and 1842 during the canalization of the Vilaine to improve shipping. This project was crucial for developing the region's economy and connecting communities along the river.

The lock reflects how 19th-century society sought to control the river for commerce and transportation. Walking along the canal, you can sense how this infrastructure shaped daily life and trade patterns in the region.

The lock is located on Allée Louis Lucipia and remains freely accessible from the surrounding area. Plan your visit for regular working periods to ensure you can see the structure and the canal without disruption.

The lock was designed by several skilled surveyors whose names appear in 1842 cadastral records. These professionals were instrumental in precisely mapping and constructing this river engineering project.
