Second World War defenses along the southern boundary of St Hereson School visible on wartime aerial photographs centred at TR 3921 6696. The defences comprised slit trenches along the outer side of the boundary and a parallel line of barbed wire within the school grounds. A second line of barbed wire extends northwards around the pillbox and along the side of the road stopping short of the school. The slit trench was a simple linear ditch on the eastern side, but becomes more complex system of ditches bulging southwards from the boundary presumably accommodating gun emplacements.At the western end a single pillbox was located at TR 3911 6698.These have been mapped from aerial photographs as part of the Historic England: Ramsgate HAZ project.

Description from record MWX43071:
Second World War defensive features, including slit trenching, gun emplacements and barbed wire, located at the southern boundary of St Hereson School, mapped from military aerial photographs taken in 1941 and 1942.

Defensive features are first visible in January 1941 [1], comprising two circular gun emplacements with central pintles, located beside the railway track along with two small areas of slit trenching situated at the southern boundary of the school, approximately 140m apart. These measure approximately 30m and 17m. By May 1942 [2] the two trench systems have been linked by a long slit trench running along the school's boundary although the earlier slit trench to the east looks backfilled by this date. The only other addition by May 1942 is the quantity of barbed wire visible, enclosing several of the military features.

Other features seen on the 1941 photographs include three structures that are not visible on the 1938 Epoch 4 1:2500 historic mapping so were presumably constructed for a military purpose. They are located in a row in a field adjacent to the school and each measure 7m by 5m. Along the southern edge of Dumpton Park Drive there are other signs of military defence features including a short length of trench (measuring 9m in length) and bank, two more short lengths of ditch. At the junction with Dumpton Gap Road a small structure is visible on the January 1941 photographs, measuring 3.5m by 3m and is a possible pillbox. Close to the southern-most gun emplacement there is another series of slit trenching and banks.

The barbed wire is gone by April 1946, and the two gun emplacements by April 1950. The remaining features are all still apparent on photographs taken in April 1950 but the area is fully developed as housing by 1973.

St Hereson School was formerly the Holy Cross Convalescence Home (for girls) and was closed during the Second World War, presumably being commandeered by the military being in close proximity to the Dumpton Gap Anti-Aircraft battery to the south, and thus the reason for extra defence features at the southern boundary.
