It is recognised as one of the finest churches of the first half of the C20 and the masterpiece of Edward Schroeder Prior. The church has a 5-bay nave 52' wide with an extraordinary single span roof with thick, deep arches that spring low from massive walls. The chancel is narrow, shallow and tapered towards the east end. The nave walls are 3'6" thick at floor level, which reduce to 2'6" at window sill height. The transverse nave arches basically follow the design at Holy Trinity but the span of the roof is 42' instead of 29'. They are brought down into the church as internal buttresses. The buttresses are pierced to make side passages, the weight being transferred to paired columns of a pattern of Saxon origin, with simple cushion capitals similar to those depicted in William Lethaby's The Church of Sancta Sophia, Constantinople. The stone masonry is of local Marsden limestone from a quarry three miles north of the site. The roof is covered in Yorkshire slate. The project is to carry out urgent structural repairs.
