Located on the western outskirts of the modern-day suburban town of Raheen, it was operational from 1882 until 1974 when it closed as a school for the last time.
This was largely due to the influence of Lord Monteagle of Brandon, a former Chancellor of the Exchequer in the British Government and a good Irish landlord.
In 1850 a young priest of the Diocese of Dromore was received into the order of the Society of Jesus; his name was Fr.
In 1872 he was appointed rector of the Sacred Heart Church and Crescent College, Limerick, a position he was to occupy for the next ten years.
With some difficulty this permission was obtained and Fr René was in Limerick for the opening of the apostolic school at Crescent House in September 1880.
However the apostolic school alone was not a viable proposition so he persuaded the Bishop of Limerick to send the diocesan seminary back to Mungret.
The apostolics moved to Mungret on 10 August 1882, and were joined by the seminarians on 14 September that year.
Shortly after its founding a new Bishop of Limerick decided to house the seminarians in the city where they would be nearer the cathedral.
