TQ 7592 7163. A gun emplacement or slit trench, probably dating to the Second World War, is visible as earthworks on aerial photographs and has been mapped as part of the English Heritage: Hoo Peninsula Landscape Project. The site comprises two parallel banks about 27m long, on either side of a ditch. It is located on Hoo Common near a Second World War military camp, and may be associated with it. Several other gun emplacements and slit trenches are located in the immediate vicinity. (1-2)

Alternatively, the gun emplacement could be associated with First World War practice trenches and redoubts in the same area. This part of Hoo Common is noted on a War Department map of Lodge Hill field defences, 1914-16, as part of the "New field works ground", the greatest extent of which was located to the west, below Chattenden Barracks.
