One of the finest medieval churches in South Yorkshire, All Saints contains "in its north door the best known and most spectacular piece of pre-Conquest architecture in South Yorkshire" (Ryder 1982, 71). Other (possibly reused) Saxon masonry can be seen within the church building. Ryder (ibid) speculates that the Saxon North Portico may have formed one limb of a 'crossing' of a major Saxon church such as at Stow in Lincolnshire. This theory would involve the migration of the church plan east after the Conquest as a consequence of the construction of the Norman motte to the west of the present tower. The church is thought to have experienced major reordering and rebuilding in the Norman period c1100 and again in the 14th century (resulting in the majority of the present 'Perpendicular' windows and the dominant tower and spire). Unknown legibility of earlier use of the site.
