The Saint Louis Priory School, a Roman Catholic secondary day school for boys, is located on a 150-acre campus in Creve Coeur, suburban St. Louis, Missouri, within the Archdiocese of Saint Louis. The school is run by the Benedictine monks of Saint Louis Abbey as part of their religious ministry.HistoryThe school was established in 1955, at the invitation of St. Louis Catholics, by monks of the Benedictine Ampleforth Abbey in Yorkshire, England. The corresponding Priory of Saints Louis and Mary (now Saint Louis Abbey), a Benedictine monastery, was established at the same time. The Priory, which is a member of the English Benedictine Congregation, became independent of Ampleforth in 1973, and was elevated to an Abbey in 1989.The founding Prior (1955–1967) was Reverend Columba Cary-Elwes, an author, monastic leader, and former titular Abbot of Westminster. The founding headmaster was scholar and author Rev. Timothy Horner, O.S.B., who also founded the school's first athletic team, the Rebel Ruggers.
