Second World War Radar Station established by January 1940. The station was sited to provide warning of aircraft approaching the Thames Estuary and London. It played an important role in the defence system used during the Battle of Britain and was attacked on 15th August 1940. The site was more substantial than most radar stations, consisting of transmitter and receiver arrays, a transmitter and receiver hut, a power house and general hut but also a large underground structure and an above ground structure camoflaged as a domestic house along with a 200 ft tower.(1)

In the early 1950s the site was chosen to be a ROTOR station but it was downgraded in the later 1950s and the bunker was sealed in the 1960s. (2)

Components of a Chain Home Low Station located on Foreness Point, designated CHL03B, were mapped from aerial photographs during the Historic England Isle of Thanet Project in 2024.

The site of a Chain Home Low radar station at Foreness Point, which was established by March 1940. The station provided early warning for low-flying enemy aircraft approaching the Thames estuary and London.

Chain Home Low sites typically comprised two gantries carrying the transmitter and receiver aerial arrays, a transmitter and receiver hut, a standby set house for the reserve power, and a general purposes hut. Aerial photography from 1995 shows that the station had been removed. A second Chain Home Low station on Foreness, site CHL03A, was located immediately to the north. Elements of the two sites have been confused in previous HER/Historic England records and it is not clear from the aerial evidence precisely how to divide Second World War features on Foreness Point between the two sites. Further research is required to clarify the nature of the two stations and their respective structures.

Components of the ROTOR station mentioned by authority (2), also mapped during the Historic England Isle of Thanet Project, are recorded separately.
