This modern oratory symbolically replaced a large chapel, unfortunately destroyed during the Battle of Saint-Nazaire, which was on the other bank, on the Guenrouet side, occupied by the Germans. It is a very pleasant section of the Nantes-Brest Canal, much wilder due to its vegetation and the meandering river.

Small port with a dozen moorings. Tourist office, pedal boat and kayak rentals, etc., and numerous picnic tables in the shade of the trees. A perfect place for a break.
