Mont Blanc’s summit is in France.

Mont Blanc (French) and Monte Bianco (Italian) means “White Mountain” for its perpetual snowfields and glaciers.

The summit of Mont Blanc is a thick, perennial ice and snow dome whose thickness varies. No exact and permanent summit elevation can therefore be determined, though accurate measurements have been made on specific dates.For a long time its official elevation was 4,807 meters (15,771 feet).


The first recorded ascent of Mont Blanc was on 8 August 1786 by Jacques Balmat and the doctor Michel Paccard. This climb, initiated by Horace-Bénédict de Saussure, who gave a reward for the successful ascent, traditionally marks the start of modern mountaineering.

The first woman to climb Mont Blanc was Marie Paradis in 1808.

The first dog without human technical help was “Tschingel” from Grindelwald. When Tschingel climbed the Mont Blanc as usual with her own paws (1875), she was observed from Chamonix with the telescope and her arrival on the summit was celebrated with a cannon shot.


About 20,000 climbers climb Mont Blanc annually and the area surrounding the mountain has become a major tourist area for both Italy and France.

The first professional scientific investigations on the summit were conducted by the botanist-meteorologist Joseph Vallot at the end of the 19th century. He wanted to stay near the top of the summit, so he built his own permanent cabin.

French astronomer Jules Janssen had the ambition to create the highest observatory in the world. An observatory stationed at the summit of Mont Blanc would give a clear view of the sky. Janssen’s observatory, built in 1893, was at the highest peak and susceptible to extreme weather. Levers attached to the ice supported the observatory. This worked to some extent until 1906 , when the building started leaning heavily. It was abandoned and eventually the building fell.

The mountain was the scene of two fatal air crashes; Air India Flight 245 in 1950 and Air India Flight 101 in 1966.
