Clongowes Wood College has the reputation of being one of the leading schools in Ireland. It is also one of the oldest having been established in 1814 when it received its first pupil, James McLorinan of Dublin. The Castle in which the Jesuit Community lives was originally built around 1450 and has been renovated on a number of occasions since.

Historically, Clongowes has educated many pupils who have gone on to play important roles in Irish political, economic, social and literary life. Boys are regularly reminded that privilege carries responsibilities and that each boy has an obligation to strive for the betterment of society.

Due to its history, the school has a number of established traditions including Union Day held in May when parents and pupils gather for the graduation Mass, the end of year prize-giving and picnic. Other significant occasions include School Mass at the beginning of the year, Patron’s Day (St. Aloysius Gonzaga), feast of St. Stanislaus Kostka, Christmas Carol Service, Confirmation and House Sports’ Day.
