Tadworth is a big suburban town in Surrey in the south-east of the Epsom Downs, part of the North Downs. It develops part of the Borough of Reigate and Banstead. At the 2001 census Tadworth had a population of 9,522. Neighbouring settlements include Walton-on-the-Hill, Kingswood, Epsom, Burgh Heath, Banstead, Reigate. Tadworth lay within the Copthorne hundred, an administrative department designed by the Saxons and later adopted by the Normans. There are no gutters draining pipes the location as the chalk quickly takes in water on the Downs. The Tattenham Corner Branch Line develops a deep, curved cutting running previous gardens in the centre of the town as it relies on the racecourse to the north, and arrives from a tunnel promptly south of the Tadworth Roundabout preserving the carefully wooded health there. The village adjoins in its north-west edge the top of Langley Vale, topped by the Iron Age room in South Tadworth Farm. Epsom Downs Racecourse is home to The Derby and creates a contiguous development with the Tattenhams, a ward including: the neighbourhoods of Great Tattenhams in the north by Nork, Banstead; Little Tattenhams as well as Tattenham Corner.
