Grande Chartreuse, Carthusian monastery in Saint-Pierre-de-Chartreuse, France.

Grande Chartreuse is a Carthusian monastery in the Chartreuse Mountains, structured around a central courtyard with individual monk cells and shared spaces. The complex combines private living areas for each monk with common prayer rooms and service buildings.

Bishop Hugh of Grenoble installed Bruno and six companions in the Chartreuse valley on 24 June 1084, and a donation charter of 9 December 1086 ratified the gift of some 1,700 hectares. Eight fires between 1320 and 1676 destroyed the buildings; after the last, Dom Innocent Le Masson rebuilt the monastery in the form seen today. The monks were expelled in 1790 and returned in 1816 under a royal ordinance.

The monastery is placed under the patronage of John the Baptist because tradition holds that Bruno and his six companions settled in the valley on 24 June 1084, his feast day. The Carthusian customs of 1127 call reading "the food of the soul", and the house kept a large library, partly destroyed over time by fires, avalanches and looting.

The monastery itself is not open to public visits, but the Museum of Grande Chartreuse nearby offers insights into Carthusian history and monastic life. Visiting the museum helps travelers understand the monks' way of living and learn about the order's traditions.

The liqueur recipe was reportedly given to the monks in 1605 by Marshal François Annibal d'Estrées; they spent over a century refining its 130 ingredients. In 1764 they enlarged the distillery, later moved several times because of explosion risk. In 2015 the order sold 1.5 million bottles.
