Founded by the Holy Ghost Order in in 1890, St Mary’s College Senior School has 440 boys, with a tight-knit sense of community and shared values. We are proud of what we are: a small school where everybody knows everybody else; an academic school in which students are expected to go to Third Level; a sporting school that punches above its weight; a missionary school with strong links to the developing world.


We are deeply saddened at the news of the death (in New York) of our past student Rónán Lennon, class of 2009. Our thoughts and prayer are with his parents Noreen and Gerard, brother Ciarán, and sister Aoibhín.
