Tadworth is a large suburban village in Surrey in the south-east of the Epsom Downs, part of the North Downs. It forms part of the Borough of Reigate and Banstead. At the 2001 census Tadworth had a population of 9,522.HistoryNeolithic and Roman period in BritainOn a small farm to the north-west, South Tadworth Farm, directly at the top of the westward-facing Langley Vale and south of the Epsom Downs racecourse, is an Iron Age Banjo enclosure, a term used by archaeologists for a distinctive type of prehistoric settlement. They were mostly constructed and used during the Middle Iron Age (400–100 BC), although some remained in use up to the time of the Roman Conquest (43 AD).There are three more rectangular inclosures, which may be mentioned here as being connected in all probability with the settlement of which this villa was part, though they are actually over the border of Banstead parish. Two of these are south of the two windmills south of Tadworth. They are well-marked, nearly square inclosures, with a mound and ditch and gateways to the east or south-east. They are east of the road from Betchworth to Banstead. The third is west of the road, and very close to Walton village; but though on land known commonly as Walton Heath, is actually on the Banstead side of the boundary. It is larger than the others, less well-preserved, and with a gateway to the north-west. Roman tiles may be found in or near all three. These inclosures have been commonly referred to as the 'Roman Camps' on Walton Heath, but it is not obvious that they were camps.Dark and Middle AgesTadworth appears in Domesday Book of 1086 as Tadeorde and Tadorne. It was held partly by Halsart from William de Braiose and partly by Radulf (Ralph) from the Bishop of Bayeux. Its domesday assets were: 2 hides. It had 5 ploughs, woodland worth 4 hogs. It rendered £3 15s 0d. Manorialism operated for the ensuing centuries.
