The Chemin de la Mâture is a 1200 meter long tunnel carved into the cliff. Its work is ordered by Louis XV to allow the exploitation and the routing of the trees of the steep-sided valley. Below. The trunks of these trees grew extremely straight due to their very vertical exposure to the sun. This verticality thus promised masts of a rare quality to the fleet of the Royal Navy.

View of the Fort du Portalet

Highlight • Viewpoint

Leaning against the cliff, and facing the path of the mast, the fort of Portalet was initially built to protect the road to the Col de Somport.
It will serve as a penitentiary center for many political figures under the Vichy regime.
