The church consists of nave, S porch, N aisle, N chapel, chancel and W tower, built of rubble limestone with some ashlar. The church and churchyard lie close to the angle of two roads, opposite a park.

Items of interest to the Corpus are the S doorway to the nave and a sedilia and piscina built into the S wall of the chancel; remnants of windows and a doorway survive in the same wall.

Adwick-le-Street takes its name from the Roman road between Doncasterand Castleford, the suffix distinguishing it from Adwick-on-Dearne. The road also forms part of the parish boundary with Brodsworth. The settlement is named in Domesday Book, but the first mention of a church is when it was given, c.1170x1181, to the Cistercian nuns of Hampole Priory two miles away (Hunter 1828, 352-6; VCH 1913, 163). There is however a reference to Hampole in existence as a Benedictine house in 1156 (English Heritage/National Monuments Record website), in which case the gift, although unrecorded, may have been 1156x1181.

The church is oriented in the same unusual direction as St Wilfrid, Cantley, i.e. NE, and may suggest that the site both of were influenced by some earlier feature (Brooks 1997, 2). Plan showing building periods in Brooks 1997, 3.

Ryder 1982, 88, says the church was ‘over-restored’ in 1862. He singles out the S doorway as ‘much restored’. Perhaps that explains the lack of a label and the curious capitals.

Pevsner (1959; 1967, 74) considers the sedilia contemporary with the C13 N chapel, ‘or a little earlier’. Ryder 1982 does not mention the sedilia or piscina. The sedilia interferes with one of the blocked windows in the same wall and is therefore presumably later than the window.

It might be that the two loose stones on the nearby sill were formerly part of the sedilia.
