Components of a Chain Home Low Station located on Foreness Point, designated CHL03A, 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 January 1940. The station provided early warning for low-flying enemy aircraft approaching the Thames estuary and London. It formed part of the warning network for 11 Group RAF Fighter Command during the Battle of Britain. As such it was attacked by the Luftwaffe during all-out German air assaults on 15th August 1940.

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 CHL03B, was located immediately to the south. 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.
