The Defence of Britain Description: The site of a Royal Air Force Chain Home Low radar station at Marks Castle established by October 1940. Chain Home Low (CHL) stations provided early warning of approaching low-flying enemy aircraft during the Second World War. CHL 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.
Defence measures installed at radar stations included Light Anti-Aircraft gun emplacements, pillboxes, road blocks and air raid shelters. Aerial photography from 1987 shows the remains of building bases at the site, and the possible remnants of aerial plinths. Designation: CHL17A Marks castle.Source: NMR Click here for more details EDOBID: e25129Last Edited: Images: None
