Monte Grammondo, Mountain summit in Liguria, Italy

Mont Grammont is a 1,378-metre summit on the Italian-French border ridge, in the Maritime Alps and Préalpes de Nice. It is built of Jurassic limestone about 170 million years old. The top, entirely in Italian territory, holds a small geodetic pillar; on a shoulder at 1,377 m just west of the summit stand a large cross, a border stone and a memorial to the fallen.

The summit area holds a geodetic pillar, a large cross, a border stone and a memorial to the fallen on a shoulder at 1,377 m just west of the top. The mountain lies on the Italian-French border crest, with the Cornà pass separating it from Cima Longoira to the south and the crest continuing north toward the Traittore pass. Its Jurassic limestone, about 170 million years old, forms the ridge.

The Italian name Monte Grammondo and the French Mont Grammond both derive from a root meaning "big mountain". On the 1,377-metre shoulder just west of the summit stand a large cross, a border stone and a monument to the fallen, where walkers coming up from the Bevera valley villages stop.

The summit is reached on foot from Sospel in France, from Olivetta, Torri, San Pancrazio and Villatella in the Bevera valley, and from Castellar and Castillon above Menton; the route from Villatella passes the Col du Cornà. Near the top, at 1,010 m, stands the Rifugio Patrick Gambino, owned by the CAI of Ventimiglia, rebuilt in 1995 with 14 beds.

The mountain marks the western Alpine limit of a resident Alpine chamois population, the closest to the sea in the range. The herd lives semi-isolated, with numbers changed only by births, deaths and wandering young, so an outbreak or disaster could wipe out the species here.
