 After only two and half years the school moved to St. Mungo Street, Townhead, and in 1883 overcrowding led the school to move again, this time to Parson Street also in Townhead where it remained until 1973.In the wake of the Education Act of 1918 the demand for admission to the school surged.In 1919 the school was absorbed into the state system, while retaining its Roman Catholic character under the running of the Marist Brothers.
