Academic life The school aims for a low teacher/pupil ratio, and has a range of computing and science laboratories. The school's Alton Library, a reference and lending facility, is the largest second-level school library in Ireland. Sporting tradition Sporting facilities at the school include nine rugby pitches, one soccer pitch, a cricket crease with pavilion, table tennis room, state of the art tennis courts, a fully equipped weights room and an athletics track. Sport has been played at Castleknock since the foundation of the college. Throughout the mid-nineteenth century a game peculiar to Castleknock, known as stilts, was played by the entire student body on a gravel patch in grounds. Owing to the often over-zealous efforts of the participants this game was discouraged by the college fathers in favour of soccer, which was the game of choice among students of Castleknock until 1909 when it was replaced by rugby as the college's primary sport. In 1918 the college won the Leinster Colleges Senior hurling championship. Shortly afterwards the college concentrated more on rugby and the playing of Gaelic games became less prominent. Rugby Rugby posts were first erected in the college in November 1909. The school has won the Leinster Schools Senior Cup on eight occasions since first entering (and winning) the competition in 1913. Castleknock teams have been runners-up in the competition on fifteen occasions, contesting more finals than any other school apart from Belvedere College and Blackrock College. The Leinster Schools Junior Cup has also been won on eight occasions, the last time in 1966. Castleknock is considered to be one of the Major Leinster Rugby Schools, the others being Blackrock, Clongowes, Belvedere, Terenure, St Michael's and St Mary's. The college appointed Adrian Flavin, a former Ireland rugby player, as director of rugby in the year 2013. 26 past men have represented Ireland at full international level, the most recent being Leinster Rugby's Devin Toner (class of 2004) who has been capped on seventy occasions. Toner is one of two past men to have won the Heineken Cup (2009, 2011, 2012) with Denis Hurley of Munster Rugby lifting the trophy in 2008. Past men James Leo Farrell and Michael Dunne were part of the British and Irish Lions touring squad to New Zealand and Australia. Farrell had also played for the Lions on the 1927 tour to Argentina.
