Céad míle fáilte. I would like to welcome you to the St. Mary’s Boys’ National School website. St. Mary’s is a Catholic vertical primary school (Junior Infants to sixth class) situated in Lucan Village (St. Mary’s Parish) and is ten kilometres west of Dublin city centre. Our school was founded in 1864 and was originally located beside St. Mary’s Church. We moved to a new five classroom school on our current site on Chapel Hill in 1965 and have since grown to twenty classrooms with 524 boys and 40 staff.
