Rushett Common

From the Wikipedia page on Malden Rushett

South of Malden Rushett is Rushett Common consisting of two strips of woodland alongside the A243 to the edge of the boundary between Greater London and Surrey.[3] These are bounded by the Surrey woodlands of Princes Covert to the west and Epsom Common to the east. Within Rushett Common is Telegraph Hill - earlier known as Cabbage Hill - which was the site of a station on the Admiralty Shutter telegraph line. This used the shutter system to communicate between London and Portsmouth from 1796 until 1816. The buildings were small two-roomed wooden huts with a frame which held the six wooden shutters.[4] The station was replaced by a semaphore station built at Claygate.
