Welcome to the Catholic University School

Catholic University School (C.U.S.) is a private, Catholic secondary school for boys in Dublin, Ireland. Under the Trusteeship of the Marist Fathers, CUS is located in the heart of Dublin, on Lower Leeson Street. The Marist Order was founded in 1836 and almost immediately the Marists set up schools which emphasised excellence in learning and provided a context which would develop a pupil’s sense of values in accordance with the Gospel. We believe passionately in the value of the education that we provide to the pupils who attend Catholic University School.
