St. Peter's church on Mill Road is the main Church in Wales parish church within the village while the Roman Catholic congregation worships at St. Mary's church on Edith Road. St Peter's Church was built in order to replace the old "Iron Church" in the village square in 1929–1930. The previous "Iron Church" serviced as a Chapel of ease for St. Andrews since 1881 but could only hold 180 worshippers. The Foundation Stone was laid on St. Peter's Day on the 29 June 1929 and was consecrated on 15 October 1930. The Church was designed by the notable Glamorgan architect, J Coates Carter, and was built after his death. Much of the masonry was re-used from the recently demolished Cyfarthfa iron and steel works. St Peter's Church is currently a grade two listed building.
