History

St Mary’s C.B.S. traces its origins to 1847 when Edmund Rice established a small school on Tower Hill, one of the first outside Waterford and Dublin. The original corner stones from that site were relocated in 2010 to the current Borris Road entrance. In 2010 the school opened its new campus to 500 pupils and has since expanded its enrolment and facilities, celebrating the 175th anniversary of its founding in 2022.
