Conception Abbey, site of the Basilica of the Immaculate Conception, is a monastery of the Swiss-American Congregation of the Benedictine Confederation. The monastery, founded by the Swiss Engelberg Abbey in 1873 in northwest Missouri's Nodaway County, was raised to a conventual priory in 1876 and elevated to an abbey in 1881. In 2021 the community numbered fifty-eight monks who celebrate the Eucharist and Liturgy of the Hours daily and who staff and administer Conception Seminary College, the Printery House, and the Abbey Guest Center. Monks also serve as parish priests and hospital chaplains in the Roman Catholic Diocese of Kansas City-Saint Joseph and other dioceses. There is also a large postal facility attached to The Printery House, operated by lay employees, which includes package shipping and delivery facilities.
