Mont Blanc is the highest mountain in the Alps and Western Europe, rising 4,808 m (15,774 ft) above sea level. It is the second-highest and second-most prominent mountain in Europe, after Mount Elbrus, and it is the eleventh most prominent mountain summit in the world. The mountain stands between the regions of Aosta Valley, Italy, and Savoie and Haute-Savoie, France. It gives its name to the Mont Blanc massif, which itself forms part of a larger range referred to as the Graian Alps. The location of the summit of Mont Blanc is on the watershed line between the valleys of Ferret and Veny in Italy and the valleys of Montjoie, and Arve in France, on the border between the two countries. Ownership of the summit area has long been a subject of historical dispute between the two countries.
