A Second World War anti aircraft site and a Light Anti Aircraft Diver battery are visible as earthworks, buildings and a structure on aerial photographs taken in 1941 and 1946. The earthworks are visible as a soilmark and the structure has been removed on aerial photographs taken in 1966. The diver battery comprises a line of at least 6 gun emplacements surrounded by barbed wire obstruction. This was armed with eight 20mm Polsten guns, and was manned by H3/2722 RAF Regiment when it was deployed here on 2nd August 1944. The diver battery has incorporated an earlier anti aircraft site which comprises an observation post, three gunposts and four military buildings. The largest of these is a Nissen hut, and is flanked by a berm to the seaward side. This site has been mapped from aerial photographs as part of the South East Rapid Coastal Zone Assessment Survey NMP (Component 2).
