"Some late Norman or Transitional work survives in this much restored church. The three bay north arcade has round unmolded arches, and some of the chancel lancets are old, the apse being an addition of 1891. Inside is a fragment of a late Saxon cross shaft" (Ryder 1982). The pre-conquest settlement of Mexborough was shared between 3 Saxon lords (Domesday 10W 13) with the same source noting a significant decrease in value following the conquest. This Saxon settlement may well have been a fortified Saxon 'burgh' (hence the placename) or fortified settlement. Unknown legibility of earlier landscape. Probable 19th century vicarage included within this polygon.
