The fragmented cropmark traces of curvilinear and rectilinear ditch-defined features thought to be the remains of First or Second World War buildings and structures located at TQ 8893 7670 in a playing field immediately to the west of Grain Fort. In the centre of the the site (at TQ 8893 7769) is a circular ditch (7m in diameter) with a central pit which could be the remains of a searchlight emplacement. To the north-west at TQ 8891 7671 the faint remains of a possible sub-circular ditched enclosure 6m in diameter could be seen, and to the south-west at TQ 8892 7668 a 5/6 sided ditched enclosure measureing c.4.5m in diameter could be seen.

These features were mapped from aerial photographs taken English Heritage in August 2011 as of the English Heritage: Hoo Peninsula Landscape Project. The site of a WW1/WW2 camp recorded from 1942 RAF photographs lies immediately to the north of these features (NMR Amie Monument Number: 1541951). (1)
