The American-Cassinese Congregation is a Catholic association of Benedictine monasteries.
The Congregation consists of 20 independent monasteries with houses or dependencies in 16 of the United States, Puerto Rico, and in six other countries on three continents.
Abbot Boniface Wimmer OSB, founder of Saint Vincent Archabbey in Latrobe, Pennsylvania, created the Congregation, and placed it under the patronage of the Holy Guardian Angels. Pope Pius IX erected it as a monastic congregation on 24 August 1855.
Our monasteries follow the Rule written
by Saint Benedict of Nursia (480-547).
