St Mary's church is located on the north side of Holton Road. It was designed by G.E.Halliday, exhibited in 1901 and built in 1903-5 but left unfinished.
It is made with walls of squared, rock-faced Lias with Bath stone dressings. It comprises an aiseld nave and Decorated chancel, both handsomely roofed. Close to the street the south aisle presents an array of four huge Perpendicular between buttresses. The intended south-west porch and south-east tower were not built. Handsome six-bay arcades, the piers with four shafts four big hollows point to a Perpendicular north aisle as yet unbuilt. The font is grossely neo-Norman and may not be a design of Halliday.
