The Mont Blanc is the highest mountain of the Mont Blanc Massif and one of the highest peaks in Europe. The summit lies at the border between France and Italy. French cartographers claim three of the principal peaks (of which the Mont Blanc is one) within its territory, but this is disputed by the Italians who place the border right on the top of the mountain. This claim is backed up by locals from both sides who suggest the summit should be shared. The first recorded ascent was made on 8th August 1786, marking it the start of modern mountaineering.
