O.C.S.O.

The Order of Cistercians of the Strict Observance (also known as “Trappists”) is a Roman Catholic contemplative religious order, consisting of monasteries of monks and monasteries of nuns. We are part of the larger Cistercian family which traces its origin to 1098. As Cistercians we follow the Rule of St Benedict, and so are part of the Benedictine family as well. Our lives are dedicated to seeking union with God, through Jesus Christ, in a community of sisters or brothers.
