On 24 May 1853, the foundation stone of the church was laid by the Bishop of Beverley, John Briggs. The architect was Joseph Hanson He also designed Plymouth Cathedral and the Church of St Walburge in Preston, both of which, like Mount St Mary's Church, is in the Gothic Revival Style In the same year, Mount Saint Marys School was founded next door to the church. It was staffed by the Sisters Oblates of Mary Immaculate. They were housed in a nearby convent and also used the church as their place of worship.
On 29 July 1857, the church was dedicated in a ceremony presided over by Bishop Briggs The ceremony was notable because in attendance were the Archbishop of Westminster, Cardinal Nicholas Wiseman his successor Henry Manning and the founder of the Oblates, Eugene de Mazenod who was made a saint in 1995. They processed through the city streets before having Mass in the church.
The church was not complete; only the nave and side aisles were built. The chancel and transepts were designed by Edward Pugin who was a partner in Joseph Hansom's architectural firm from 1862 to 1863. When the chancel and transepts were completed, the church in its entirety was opened on 13 September 1866. The main celebrant at the ceremony was the Archbishop of Westminster Cardinal Manning
