The original primary school in Ballinlough was co-educational and was situated in Churchyard Lane. In 1965 St. Anthony's B.N.S. was built in Beechwood Park. The school had ten classrooms and Mr. Jack Corkery was principal.
Mr. Bart Whooley became principal in 1974 and as numbers had increased in 1977/78 a new extension was built providing six new classrooms and a small hall. In 1993 Mr. Flor O'Sulivan was appointed principal, and over the next few years a fund-raising initiative raised a substantial sum of money and in 1997 a new sports hall and six additional classrooms were built.
Over the next few years further extensions provided thirteen extra classrooms, computer room and conversion of the attic, in the original school.
At Present, we have 807 pupils, 41 teachers, 13 snas, 1 secretary and 3 caretakers.
