The Carthusian Order, also called the Order of Saint Bruno, is a Catholic religious order of enclosed monastics. The order was founded by Saint Bruno of Cologne in 1084 and includes both monks and nuns. The order has its own Rule, called the Statutes, rather than the Rule of Saint Benedict, and combines eremitical and cenobitic life.The name Carthusian is derived from the Chartreuse Mountains; Saint Bruno built his first hermitage in the valley of these mountains in the French Alps.
