Founded by the Holy Ghost Order (Spiritans) in 1890, St Mary’s College Senior School has 450 boys, with a tight-knit sense of community and shared values. 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 with a noted tradition, a missionary school with strong links to the developing world.
