The present Monkstown school has been in existence for over half a century. There was a school at the bottom of Chapel Hill – at 1 de Vesci place, where the sailing club now has its clubhouse. It was a private primary school and the nuns of the Mercy Order from Passage West taught there.
There was also a National School on Chapel Hill. This was opened in 1865 and closed in 1943 when the present school was built. The boys and girls were taught separately. The boys were taught downstairs and the girls were taught upstairs. The teachers in the old school on Chapel Hill were Mr. Denis Cramer (who lived in Blackrock) and Miss McSweeney. Mr. Donal O Connor ( former Principal of Ringaskiddy N.S.) taught here too from 1948 to 1952. The boy’s entrance was on Chapel Hill and the girls entered from the Church yard. The girls crossed a stone drawbridge to get to their classroom.
This old school was unused for many years until Fr. Christy Walsh (P.P. Monkstown) R.I.P. renovated it for use as a school again in 1982. Miss Lizzy Doyle, R.I.P. a past pupil of this school performed the official opening. Mrs Ger Marnane (Principal 2006 – 2009) taught her classes there for four years. It is now operating as a Pre-School. The local St. Vincent de Paul Society and the Sea Scouts hold their weekly meetings there. The private school went on being a private school for a few years but eventually closed as the new school built in 1943 took over. In December 1938 Fr. O’ Regan purchased the present site from Mrs. O Donovan of the Glen for £69.9s.0d. Fr. O’ Regan gave the site as a present to the parish.
The new school was opened on Ash Wednesday in 1943. The original records in the school date back to 1872. The present extension was completed in 1986 under the principalship of Mr. Michael O Sullivan. The extension was built in 1986 and officially opened by Mr. Micheál Martin in 2000. The view from the top yard is spectacular – looking out towards Ringaskiddy, Haulbowline and the harbour. Once in the early years there were only 68 pupils registered but now we have 211 pupils and 12 teachers.
