The site of a Coastal Defence/Chain Home Low (CD/CHL) radar station at North Foreland. It was constructed in spring 1941 by the British Army to detect approaching ships and aircraft during the Second World War. CD/CHL sites comprised a brick or concrete operations block with an aerial gantry mounted on the roof and a separate standby set house for the reserve power. Staff were billeted where possible, but some stations had a small layout of domestic hutting situated within one mile of the site. The site was upgraded by the Royal Air Force in 1942 and fitted with centimetric radar to become a Chain Home Extra Low station, called site K5. Aerial photography from 1979 shows that the station had been removed and the site given over to agricultural use.
