The Glomel Cut

Highlight (Segment) • Monument

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.

Path between two bodies of water on the Nantes-Brest Canal

A stretch on the dam before the Trehu Moron dam.
The landscape is constantly changing. The canal meanders through the countryside here.
I love this landscape, and it's a good mood to drive here.

Gouarec Lock on the Nantes–Brest Canal

Between the Lac de Guerlédan and the double lock of Coat Natous in its section of the Côtes d´Armor, the Canal from Nantes to Brest is navigable upstream of the Lac de Guerlédan over 16 km and 10 locks. mairie-gouarec.fr/tourisme/canal-de-nantes-a-brest
The cottage next to lock 140 is only 15 Euro per night: the lock house is located on the Vélodyssée which, here, runs along the canal from Nantes to Brest.

Stone Arch Bridge on the Nantes–Brest Canal

Highlight • Bridge

Small bridge whose arc forms a semicircle, and whose reflection perfectly completes the circle. A beautiful shot to take along the Vélodyssée greenway.
