Overview
Cadw records a church of two main fabrics: a rubble-stone nave, north aisle and south porch of 1844–47 by J. J. Scoles, and a large 1894 addition in hard red brick by Edmund Kirby of Liverpool, with transeptal gables and an octagonal-roofed apse. F. R. Bates of Newport added two stone aisles in 1920. Fr James Carroll began the original church, partly endowed by Sir Josiah John Guest of Dowlais Iron Works; Carroll died of cholera in 1847 and is buried in the church. It was built for Irish migrants who came to the ironworks after the Great Famine.
Benedictines served the mission from the 1870s until 1930. Cadw notes an ornate carved stone and marble high altar and good stained glass. The church is one of four in the parish of Merthyr Tydfil, in the Archdiocese of Cardiff-Menevia. Listed Grade II on 16 August 1990, amended 12 November 2002 (Cadw 11517). A major re-roofing was completed in 2025.
