In the early years, Gaelic sports were played on part of the Howth Estate's Deerpark lands.
[4] The post-primary section of the school began on Dublin Road in 1972,[3] in a purpose-built premises built using donations of around 175,000 pounds, and with three dedicated science laboratories, and rooms for art, geography and languages.
Later lay principals were two long-serving members of staff, Richard (Dick) Fogarty (English)[6] and Raymond (Ray) Quinn (history),[7] followed, in the 2010-2011 school year, by Mary Fox.
[8] The school, which draws pupils primarily from Sutton, Baldoyle, Bayside and Howth, and also from Kilbarrack, Raheny, Portmarnock, Malahide and Clontarf, is oversubscribed with annual applications, and has a student population of over 700,[9] and is known for both academic results and sporting success.
[14] There is also a Students' Council, with delegates from every class in the school,[15] and a position of Head Boy, with a deputy, was introduced in the 2010s.
[16] The school also has a tarmac-surfaced yard, a large gym, an astro-turf pitch, and a substantial sports field with changing rooms.
[20] Other sports in which the school competes at a high level include Gaelic football, tennis, basketball, sailing and ultimate frisbee.
[27] In 2004 there was controversy when Brian McFadden - formerly of the group Westlife - released a song "Irish Son" which contained lyrics critical of corporal punishment at schools in Dublin during his childhood.
