Conception Abbey was established on 8 December 1873, by Benedictine monks of the Swiss abbey of Engelberg as a place of refuge should their monastery be suppressed by the Swiss government. They also came in response to the appeal of the Rev. James Power to minister to the spiritual needs of a colony of Irish and German settlers which he had established in northwest Missouri in 1858, prior to the Civil War. Benedictine Sisters from Maria Richenbach, a convent located not far from Engelberg, arrived in Missouri in 1873 soon after the monks, hoping ultimately to found a convent where special devotion to the Eucharist could be fostered.
