Orpington is a town in southeast London, England.  The town is situated in the London Borough of Bromley, close to the border of Greater London.  The area has been inhabited since the Stone Age.  Orpington is situated in a valley and was first known as ‘Dorpentune’, meaning ‘the village by the spring’.  It originated as a small rural village, and is recorded in the Domesday survey of 1086.  Its economy was originally agricultural, with inhabitants growing fruit and farming hops for a living.   The suburb grew considerably in the early 20th century.  Its train service was improved, and its high street was expanded to become a modern shopping centre.  Many residential areas were damaged in the Second World War, prompting an increased demand for affordable housing.  Estates sprung up in Orpington, and the town became a heavily populated suburb of London.
