What is "caterham"

Caterham is a town in the Tandridge District of Surrey, England. The town is administratively divided into two: Caterham on the Hill, and Caterham Valley, which includes the main town centre in the middle of a dry valley but rises to equal heights to the south. The town lies close to the A22, from Guildford and south of Croydon, in an upper valley cleft into the dip slope of the North Downs. Caterham on the Hill is above the valley to the west. Due to its proximity to London, Caterham is a commuter town, with small-to-medium-sized businesses of its own but relatively few business/industrial parks. It has a significant area of retail and restaurants in Caterham Valley as well as pubs dotted throughout.
