Kilnamanagh (Irish: Cill na Manach) is a suburban residential area near Tallaght, South Dublin, Ireland.
Kilnamanagh, in Irish 'Cill na Manach', translates to 'Church of the Monks', referring to the 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 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.
Former Dublin Senior footballer and current Westmeath Senior Gaelic Football team manager Paul Bealin began his career playing for St Kevin's GAA in the 1980s.
St. Kevin's Church was built in 1978, and over the years the adjoining presbytery has been residence for many priests which have included the following:
Kilnamanagh was one of the largest housing estates in Europe at the time it was built by Tom Brennan and Joseph McGowan, who traded as Kilnamanagh Estates. It is still the largest private housing estate in Europe, consisting of 1,600 houses. On release to the market, the first tranche of 3-bedroom semi-detached houses were priced at £5,995.
