"[L]arge and handsome Perp-style Commissioners' church" (Harman and Minnis 2004). Damaged during the Sheffield Blitz the church was converted in 1950 for use as a community centre. The 1950 alterations were reordered 1999 - 2000 (ibid). The church may well have been planned as an integral part of the street plan to the west from John Street to Hermitage Street, with the West Front of St Mary's neatly framed by and closing the vista along Boston Street. Fairbanks 1808 shows clearly surveyed enclosure of larger possible open fields. No legibility of older historic landscapes.
