May also be known as Saint Gregrorios Syrian Orthodox Church.
This church had fallen into disuse but now it is used for some Catholic services as well as Syrian Orthodox services and Taize prayer.
Unlike the majority of Roman Catholic churches in Ireland it has an exterior clock.
Saint Paul's on Arran Quay was designed by Patrick Byrne and it was built soon after Catholic Emancipation, when the Roman Catholic Church was beginning to build visible high-status buildings. Artistic interest is added by the altar, by Farrell (before 1863), and a copy of Rubens Conversion of St. Paul by F.S. Barff (1863), which replaced an earlier representation of the crucifixion.
