The bulk of the property in this area was built between the publication of the 1851 and 1891 Ordnance Surveys. Earlier maps show little in the way of settlement save for the small hamlets of Mortomley and High Green shown on the 1851 OS. Most of the property is terraced and was probably built to house the staff of the nearby Thorncliffe and Chapeltown works of Newton Chambers although significant numbers of older vernacular buildings predating the 1851 OS are present especially at the centre of Mortomley. A large number of contemporary public houses, inns, halls and places of worship are also present including both C of E and Catholic churches and graveyards as well as sundry Methodist chapels. These may be indicative of a diverse population drawn from a wide geographic population in the 19th century. Regular road pattern shown on 1851 OS to the west of Mortomley may reflect parliamentary enclosure and give fragmentary legibility of this former land use. Possibly former common land (?the High Green). Important representative group of 19th century and early 20th century industrialised settlement.
