Father Jeremiah O'Connell O.S.B. was a missionary priest who had built St. Mary's College in Columbia, South Carolina, but it had been destroyed during the Civil War.. In 1876 he bought the 500-acre former Caldwell farm and donated it to the Benedictines of Saint Vincent Archabbey in Latrobe, Pennsylvania in hopes they would establish an educational institution in North Carolina. Under the direction of Abbot Boniface Wimmer of the Bendictines set about to establish a monastery and college. The monks constructed the buildings from red clay. In 1884, the monastery was designated by the Holy See as Mary Help of Christians Abbey and Father Leo Michael Haid was elected the first abbot, a position he held until his death in 1924. In July 1886, the first three novices professed vows and an alumnus of the college became a novice. That same year, Haid founded a seminary at Belmont. On February 4, 1888 he was appointed Vicar Apostolic of North Carolina and was consecrated bishop at the Baltimore Cathedral by Baltimore Archbishop Cardinal James Gibbons on July 1, 1888, becoming the first American abbot-bishop. In May 1891 the Grotto of Our Lady of Lourdes was dedicated as a pilgrimage shrine by Abbot Haid. Katharine Drexel, a benefactor of the monastery and college, visited Belmont Abbey in 1904.

In 1944, its territory, except for Gaston County, was given to the Diocese of Raleigh. In July 1960, Gaston County too was placed under the Diocese of Raleigh. In 1977, its status as a territorial abbey was suppressed under the Diocese of Charlotte.
