The monks are present on the territory since 1173, when the upper part of the Valley is given to the prior Uldrico of the Carthusian order. The lands are divided in granges, small farms controlled by the monastery. The monks create first a correria, house of the lay-members of the monastery on the left bank of the Pesio, then the works for the Carthusian monastery start on the opposite bank of the stream, on a territory rich in vegetation, between the mountain and the course of the water.  In spite of the touched improvements the work of the monks isn't always appreciated by the people of the valley, who are deprived of their lands of the upper valley, first exploited for the wood-cutting, the pasture, the fishing and the picking of the products of the underwood. A great part of the current rich vegetation of the valley depends properly on the careful organisation of the lands and the management of the woods,. which we nowadays define "sustainable" and getting ahead by the monks.  

In 1802, with the arrival of Napoleon, the religious goods are expropriated and many of the works of art kept in the monastery are destroyed or lost. Afterwards the Carthusian monastery experience a temporary period of fame and splendour as an hydrotherapeutic institute, hosting famous people and then it becomes again a religious building in 1934. After long years of restoration the missionaries of the Consolata in Turin started off with an appreciated spiritual centre.
