The Cammazes breakthrough, also known as the Vauban vault or Cammazes tunnel, is a 122-meter-long and 3-meter-wide vaulted tunnel, built between 1686 and 1688, which allows the waters of the mountain ditch to reach the Saint-Ferréol reservoir. An integral part of the immense Canal du Midi structure, it has been classified as a UNESCO World Heritage site since 1996 and listed as a historic monument in 1997[1]. It was designed by Vauban in a memorandum of March 5, 1686, to channel the waters of the Montagne Noire ditch from the Sor valley to the Laudot valley, under "the crest of the Escammase mountain". Pierre-Paul Riquet, who had briefly considered this project, died in 1680. (Wikipedia)

Superb and impressive, one of the 6 (main) lakes of the Montagne Noire, do not miss following the forest track which runs along its right bank.

The way Riquet thinks about his work around the Canal du Midi remains in harmony and in no way destroys the natural beauty of the Black Mountain.

At the inauguration of the Canal du Midi (then called the Royal Canal of Languedoc), the channel of the Montagne Noire flowed into the Sor to be captured again by the channel of the plain at Pont-Crouzet. However, in order to improve water management and in particular the supply of the Saint-Ferréol reservoir, Vauban launched in 1686 a program of digging a tunnel at the level of the Cammazes so that the channel could join the Laudot and thus the Saint-Ferréol basin.

The Montagne Noire channel allows part of the water from the streams flowing naturally towards the Mediterranean side of the Canal du Midi via the Fresquel to be channeled towards the oceanic slope. It starts from the Alzeau intake to the Vauban vault, a tunnel pierced so that the channel can join the Laudot and thus the Saint-Ferréol basin then the Plaine channel.

Water management in the Montagne Noire dates back to the 17th century with the catchments created to supply the Canal du Midi. The Cammazes reservoir, filled with water in 1958 following the construction of the Cammazes dam, perpetuates the tradition and makes it possible to supply water (drinking and irrigation) to an entire region.
