A pretty iron bridge, built for farmers at the time. Here the path along the water was in a bad state in April 2026 (a warning was installed on one side of the section, but a detour through the forest is possible).

At an altitude of 184 m, the Glomel trench is the highest point of the Nantes-Brest canal and the watershed between the Blavet and Aulne basins. The canal project and its passage through the center of Brittany dates back to Vauban, the decision and the route to Napoleon. The impressive trench allows the Aulne and Blavet watersheds to communicate via the canal. The Grande Trenche of the Canal from Nantes to Brest was dug in the 19th century by deserters from the army of Louis XVIII. The 4000 convicts of Glomel had to move as much earth and rock as was necessary for the construction of a great pyramid in Egypt. It took 9 years to create this trench, more than 3 kilometers long, 100 meters wide and 23 meters deep.

This passage is the highest point of the canal. It was necessary to dig three million cubic meters of earth and rock to make the canal pass: as much as to build the largest pyramid in Egypt! The work was carried out in the 19th century by deserters imprisoned and sentenced to forced labor. Many did not survive the unimaginable working and hygienic conditions. A book “Les Bagnards du canal de Nantes à Brest” traces the little-known history of the builders of the canal from Nantes to Brest.
