An Admiralty Telegraph Station was built on Haste Hill in 1821 on part of some enclosures called Jackman's Fields. The building was of a bungalow style with the semaphore above the operating room and it was part of the semaphore line from London to Portsmouth from 1822 to 1847. The Admiralty sold the site in 1849 after the line closed, and the building underwent various additions and alterations. It is now the Whitwell Hatch Hotel.
