St. Nahi's stands on the grounds of the original monastery, having been refurbished several times, most recently in 1910, after a period when it was in use as the parish boys' school.
Following storm damage to the roof, a major refurbishment was carried out by the then Rector of the Parish, Canon William Monk Gibbon (father of the poet of the same name), who is buried in the grounds of the church.
[2] Local historian John Lennon, as well as Harry Griffith, aided by Dúchas, relocated the slabs inside the church.
An insight into life expectancy for the area can be gleaned from the "Index to the Register of Burials" for the parish between January 1897 and April 1917 show 1,836 people buried during this period, of which 551 were children under 6 years of age.
Many Irish Republican graves lie within the graveyard, including the gravestones of Lorcain McSuibhne, a member of the Irish Republican Army killed in 1922 in Kildare (his funeral occurred at St. Nahi's and there exists photographic evidence of Éamon de Valera in attendance) and of James Burke, who was killed in Croke Park on Bloody Sunday.
The Parish of Taney: a History of Dundrum, Near Dublin, and its Neighbourhood[3] published in 1895, claims that there are "tens of thousands" of burials within the graveyard, a credible figure considering its age.
As the churchyard predates the disestablishment of the Church of Ireland in 1869, it is open for burial to all those who live within the boundaries of the Parish of Taney, whatever their denomination.
