The precise age of the church is unknown. At the time of the Religious census of 1851, the parish priest William Henry Powell attested that the church had been "...consecrated from time immemorial." There is a 6th-century Ogham stone in the churchyard which may give some indication of the church's age. The original church building was restored in 1882. An extension to the nave and the porch date from 1933. The east window of the nave was designed by Mildred "Elsi" Eldridge, the wife of renowned Welsh poet R. S. Thomas. Very near to Llanpumsaint Parish Church is Bethel Presbyterian Chapel which was originally built in 1796. Nearer to the old railway line there is also Caersalem Baptist Chapel which was built in 1904. Skanda Vale, also known as "The Community of the Many Names of God", is an interfaith temple/monastery located in the Llanpumsaint Community, at a distance of from Llanpumsaint village. The temple holds festivals which are attended by pilgrims from all over the UK and even further afield. Skanda Vale also runs a hospice and is a registered charity. Valli the elephant was given to Skanda Vale as a gift from the Sri Lankan president in 1981.
