This church "has some claim to be the most interesting ancient parish church in [South Yorkshire]" (Ryder 1982, 45). The main walls of the nave are thought to be survivals from a Minster church with Portici to north and south with a western porch or tower. This church was enlarged with side aisles and a larger chancel c.1200. Ryder postulates that this development was undertaken close to the time of the rebuilding of Conisbrough Castle in stone by Hamelin Plantagenanet (ibid, 52). This date can be compared with that suggested by O'Neill for the laying out of burgage type property boundaries to the north in the Wellgate area (O'Neill 2004, 51) with his suggestion that the substantial building works of this period "would presumably have required a considerable itinerant workforce….[reflected in] a population increase in Conisbrough at this time" (ibid). The next major rebuild at the church is dated by Ryder to the later 15th century (1982, 55) with further alterations in the 17th and 18th century removed by 19th century 'restoration' (ibid, 59). Unknown legibility of earlier landscape evidence. Includes Victorian Sunday School buildings to the south.
