A small Second World War military site including slit trenches, gun emplacements, a pillbox, barbed wire, anti-tank cubes and bomb craters is visible on vertical aerial photographs of 1941 as structures and earthworks at the point where the Dengemarsh Gut Shafts meet the seafront. The structures and earthworks appear to have been removed by the time of the next available vertical aerial photograph of 1958. These features have been mapped from aerial photographs as part of the South East RCZAS NMP project.
