Alagna is one of the Alpine towns which have played a crucial role in the history of the mountaineering. The Guides Association was founded in 1872 and it is the oldest in Italy second only to that of Courmayeur (1868). From the town started all the first expeditions on the close Monte Rosa; the first one was on 23 July 1801 when Pietro Giordani, a native of Alagna, reached the summit of the peak which now is called by his name (Giordani peak, ). In 1819 Zumstein reached the third highest Monte Rosa peak (Zumstein peak, ). Finally between August the 8th and the 9th, the Alagna parish priest, reached, after three attempts, the fourth tallest peak of Monte Rosa and the highest in the Alagna Valley, the today called Gnifetti Peak ().
