The priory and church continue the long ecclesiastical history of Tallaght, built on the site of the Medieval country residence of the Archbishops of Dublin, parts of which were subsumed by the present priory. These buildings, designed by J.J. McCarthy, are characteristic of nineteenth-century institutional architecture in Ireland and provide a focus for Tallaght itself.
