The Carthusians are members of a Christian monastic order founded by Saint Bruno in 1084. They follow a strict lifestyle of solitude, prayer, and contemplation, living in individual cells within a monastery. The order emphasizes silence and simplicity, allowing monks to focus on their spiritual lives. Carthusians are known for their unique approach to monastic life, which combines communal worship with personal solitude. They typically gather for prayer and Mass but spend most of their time in silence, engaging in meditation and study. The order has a small number of monasteries, primarily located in Europe.
