The enclosure is centred at TR 0325 1776, and measures approximately 250m north-west to south-east and 206m south-west to north-east. The bank, which is formed from the coastal shingle characteristic of the area, is continuous on four sides. The south-western edge of the enclosure appears to be open. A mound of banked-up shingle is visible in roughly the centre of the partial enclosure, at TR 0328 1776. It measures 10m across, and may have been a bunker or shelter of some sort. The ground of the entire area within and surrounding the enclosure has an intensely pock-marked appearance. It is thought that this may have been caused by the repeated impacts of shelling or gunfire. This dimpled appearance continues a considerable distance onto the marshy fields to the west. The interpretation of this partial enclosure as a possible military training site is based in part on the mass of small impact craters, as well as its military context. A military firing range of possible Second World War or even earlier date (Monument Number 1539764) is visible on the same 1940 vertical aerial photographs which show the partial enclosure. This range is located approximately 450m to the east, on the same open expanse of coastal shingle. By the time of vertical aerial photographs of 1946 this whole area was in use as an armoured fighting vehicle (AFV) range. The small railway tracks which carried the moving targets of this range extend right up to the eastern side of the partial enclosure. Even earlier military remains are recorded to the west of the possible firing range or military training site discussed here. Ordnance Survey maps of 1907 and 1909 detail multiple gun targets and splinter-proof shelters in the South Brooks area of Denge Marsh. This is an area of marshy fields which has a contrasting appearance to the bare shingle to the east and west. However, the appearance of this site on aerial photographs is not immediately diagnostic of any specific period or function, and alternative interpretations may be possible. It may also be that a banked enclosure which originally had an entirely different purpose was later re-used for training purposes upon the military `colonisation┬┐ of the area. Vertical aerial photographs of 2007 show that the bank of the partial enclosure and the mass of small craters are still visible as extant earthworks (1-4).
