The De la Salle religious order came to Castlebar in 1888. Canon Patrick Lyons, who was responsible for the building of the Church of the Holy Rosary, was also responsible for bringing the order to the town.
The De La Salle established this school on a site provided by the 4th Lord Lucan George Bingham and opened the doors on 4th September 1888. There were 189 students. It is also recorded that the Earl of Lucan and his son the honourable Francis Bingham visited the school in 1889. Subjects taught at the school at the time were: Latin, Agriculture, French, Mathematics, Geography and English.
The school closed in January 1934 because of an outbreak of typhoid and closed for two weeks in 1947 because of The Big Frost. The school was destroyed by fire on the night of the 28 February 1957. Classes did not resume until 3rd April 1957 when the school was temporarily transferred to the Military Barracks, Blocks G and H.
A new St. Patrick's BNS was built behind this building and was opened on the 9th November 1961.
It is situated across the road from the Church of the Holy Rosary. It is now known as The Family Centre.
