Principal's Welcome

On behalf of our school community, I want to welcome you to the St. Mary’s Christian Brothers’ Grammar School website. I hope you enjoy reading about our school and finding out about the exciting opportunities we provide for all of our students.

St. Mary’s CBGS is an all-boys Voluntary Grammar School located on the Glen Road in West Belfast. The school was founded by the Christian Brothers’ in 1866 and moved to our current site in 1968. The school is inspired by the vision of Edmund Rice who wanted to create schools that provide excellent education and cultivate Gospel-based values. St. Mary’s continues this work today with over 1,170 students aged 11-19.

Our teachers recognise the uniqueness of every student, encourage firm friendships among the boys and foster a sense of community. It is within this caring and supportive environment that our students are allowed to develop their unique talents and become enthusiastic and highly motivated learners.
