Overlooking the village of Montsalvy, Mount Puy de l'Arbre offers a magnificent natural observatory stretching from the Mounts of Cantal to the Rouergue, passing through the Aubrac Plateau.
Near the toposcope, a granite stele reminds us that in 1798, Jean-Baptiste Delambre and Pierre Méchain measured here an arc section of the Paris meridian between Dunkirk and Barcelona. This arc measurement served as the basis for the original definition of the metre. This stele is therefore a survey marker. Picnic tables.
