The club's main grounds are located at Somerton Lane, Diswellstown. It also uses grounds managed by Fingal County Council at Porterstown, St.Catherine's Park and "Tir na nÓg" (beside Castleknock Community College).
History
The club's first major discovery was a then five-year-old Ciarán Kilkenny, whom it invited to participate in its "Tir na nÓg" sessions in 1998.[1]
The club won the National Féile in 2007 and recently 2016 and 2017.
The club has teams from juvenile to senior level. It has 1500 members from 650 different families.[2]
A clubhouse worth about €1.5 million was about to be opened in 2019, as Kilkenny was winning All-Ireland titles around him. The man who opened it, Leo Varadkar, was Taoiseach and had nephews playing for the club at the time.[1]
Lar Norton is the coach of the Castleknock senior footballers.[citation needed] Maria Bergin from Naas is the club's full-time "games promotion officer", paid by the Dublin County Board to visit local schools and inculcate the children she finds there into football and hurling.[1] She runs a nursery for four to seven year-olds each Saturday morning in Carpenterstown to the west of Castleknock.[1]
