Armthorpe village appears, from the evidence of the OS first edition mapping to have been a typical linear medieval village surrounded on three sides by common arable fields and made up of loosely planned farmsteads along one main street. Few buildings predating the 19th century are listed by Magilton (1977, 5-6) although the church of St Mary is early Norman in date and the first edition mapping indicates the ' site of ' a manor house within this area. Few early features survive within this area - the majority of the housing dates to the suburbanisation of Armthorpe from the early 20th century onwards (as communications routes to Doncaster improved and nearby pit at Markham Main drew labour to the settlement). Within this area surviving buildings include the former Rectory, nearby cottages, and Brook House Farm, all of which are shown on the 1850s mapping. The polygon also includes a late 19th century Parish Room' (first depicted 1891) giving partial legibility of the historic core.
