This is one of the very few straight sections of the canal.

Mellionnec, a municipality which is part of the Villages of Europe network, shines through art and cinema, particularly during the Documentary Film Meetings in June. This village, focused on preserving the environment, with a spirit of solidarity and having a very dynamic associative fabric, invites you to disconnect and reconnect with nature and the locals.

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.
