TR 35 SW NORTHBOURNE BITTESHANGER
1410/4/10002 Telegraph Farm
II
Pair of cottages, originally also housing a shutter telegraph, later farmhouse. Early C19. Originally two cottages which housed the operators of a telegraph station, part of a system built as a result of the Napoleonic Wars to send messages between Deal and the Admiralty in London to warn of any invasion attempt by Napoleon. The shutter telegraph, which was probably sited on the roof, no longer exists. Built of shuttered chalk and lime covered with a lime render and hipped slate roofs with brick chimneystacks. Two storeys; two windows. T-shaped on plan with attached outbuilding to rear. Windows probably casements but boarded over at time of survey. First floor windows lower in height. Gabled porch to right hand side, probably added later in C19. Rear elevation has plain door and lean-to extension. After 1815, the telegraph system was disused and the building converted into a farmhouse. The constructional technique is thought to be unique in Dover District. Historical interest as part of a chain of Napoleonic telegraph stations.
