A daughter church of the parish church of St. Michael, this was built to serve the growing population in the Forest area of the town and , perhaps, to counter the appeal of the Baptist and Methodist churches already established there. Designed by G.E. Street in the 13th century Early English style it is in ashlar with a decorative tiled roof and a bell cote, containing one bell, at the west end. It was licensed for worship in 1876 and consecrated in 1886. A spectacular interior feature is a pink and white carved marble and alabaster reredos with gold mosaic panels, presented by Mrs Ludlow Lopes in 1898. The parish registers, other than those in current use, dating from 1876 (christenings), 1890 (burials) and 1939 (marriages) are in the Wiltshire and Swindon Record Office.
