of an ancient monastery, is located in the middle of the village. In the Catholic Church, there are two parishes in the area: "Our Lady Mother of the Church", located close to the village and St Thomas the Apostle parish, Laurel Lodge. Both St Brigid's and St Thomas the Apostle contain windows from the Harry Clarke Studios. The window in St Brigid's was commissioned in 1927 by R.F. Brookes of Somerton House, Castleknock, to commemorate members of his family, whereas the Harry Clarke window in St Thomas the Apostle was donated by the Dominican Order after their convent at Dún Laoghaire closed in 1991. It depicts the Immaculate Conception of Mary. Holy wells In the townland of Diswellstown, there is a historic "rag well" - a holy well near which rags were left. Although it still flows, it was "buried" by Dublin County Council, and its site is now marked by a carved flagstone. It used to be attended especially on the eve of May 1. A second holy well, dedicated to St Brigid is located near the Church of Ireland church in Castleknock village; its spring, still flowing, has been covered by a pump for many years. Adjacent are stones with two quotations from the Bible. Local tradition held that the water of the well was safe for humans and hazardous for "lower animals." Government and representation Castleknock is located in the "Castleknock ward" for the purposes of elections to Fingal County Council. For national polls, it is in the Dublin West Dáil constituency and for European Parliament elections, the Dublin constituency.
