Duppas Hill is a park, road and surrounding residential area in Waddon, near Croydon in Greater London (and historically in Surrey). It is thought to be named after a family called 'Dubber' or 'Double'. Duppas Hill has a long history of sport and recreation. It is said that jousting took place there in medieval times and the story goes that Lord William de Warenne was treacherously slain there during a joust in 1286.
