History
Coláiste Mhuire is a primary college of education run by the Congregation of Christian Brothers. The site upon which the college now stands is only one of a series of locations where the Christian Brothers' centre of teacher training was housed. In 1831 the residence of the Superior General of the Irish Christian Brothers and the centre of teacher training was moved to North Richmond Street (O’Connell Schools) Dublin from Our Lady’s Mount (North Monastery) in Cork. In 1874 it was transferred to Belvedere House in Drumcondra (now the President’s House in St. Patrick’s College, Drumcondra). Cardinal Mc Cabe who established it as a teacher training college, now known as St. Patrick’s College, acquired Belvedere House for the Christine Brothers initially. In 1875,The Brothers moved to Marino House, on the original Lord Charlemont demesne, and have made it their home since.

Construction of a new Training College - St. Mary's Building - commenced with the laying of the foundation stone by Archbishop of Dublin, Dr. Walsh on 10th of June 1900. From its earliest days the College was involved in the training of teaching brothers who would subsequently work on the five continents.
In 1926 the Christian Brothers entered the National Schools system. Since 1971 Brothers of other orders attended the college, and since 1972 the admission of lay students to Coláiste Mhuire became a permanent arrangement. From this time the B.Ed qualification gained from Coláiste Mhuire is validated from Trinity College Dublin.
