Kilnamanagh (Irish: Cill na Manach) is a suburban residential area in Tallaght, South Dublin, Ireland.
Kilnamanagh, in Irish 'Cill na Manach' translating into 'Church of the Monks' referring to church and castle established to house Saint Kevin and his followers. Present day Kilnamanagh has close ties to Glendalough, the other resting place of St Kevin.
Unfortunately, the ancient Church of St. Kevin and castle located in Kilnamanagh were destroyed when the building of the housing estate commenced in 1974 by unscrupulous developers who were insensitive to the rich historical heritage which resided there. The well that was built by St. Kevin is now covered up, but there is still a small garden around the well for people to visit. The well and garden have been fenced in for fear of desecration. The gates that are locked and access is controlled by the local church. There are many references to St. Kevin and his followers in Kilnamanagh, the school, church and local sports teams are named after him. During the 1980s, many annual community events were held in the parish including the Sunday Fete and the annual cycle pilgrimage to Glendalough.
