The church of St John is located on St John's Terrace, on the north side of New Road, within a churchyard used as a cemetery. The church was built in 1849-50 to designs of architect R.C.Saunders, in Early Decorated Gothic style, of sandstone rubble with Bath stone ashlar dressings and slate roofs banded in two colours, with shouldered coped gables and cross finials. It comprises steep-gabled nave and lean-to aisles, aisles partly overlapping lower chancel, south porch, west bellcote and north vestry. Inside, walls are plastered, small high clerestory windows over four-bay arcades of steep chamfered arches on alternate octagonal and round ashlar columns, and a spindly exposed timber roof. Fittings include ornate marble font, pulpit and reredos, apparently of c.1870-80, in lavish coloured marbles, a First World War memorial chancel screen in oak, Perpendicular Gothic style in three bays, and a brass eagle lectern, later nineteenth century, on a cast-iron conical base. Stained glass includes works by (?) Clayton & Bell and Celtic Studios.
