CASTLEKNOCK COLLEGE – ALUMNI
The Pastmen of Castleknock College are often known as Knockmen (sometimes also Old Knockmen). The Castleknock College Union (the College’s Pastmen union / alumni association) is the oldest in Ireland and was founded by a distinguished Pastman: Charles Russell, Baron Russell, Lord Chief Justice of England and Wales. It is also one of the most active in the country organising a host of events for old boys and current pupils alike, including the annual business lunch, golf outing, tennis competitions, and a spiritual retreat. The Union also maintains a benevolent fund in aid of Pastmen and their families. In addition, the Knock Union (as it is commonly called) administers a mentoring scheme to support recent graduates of the College finding their feet in their preferred career with specific guidance from established Knockmen.
