This feature is recorded in the English Heritage report on the Second World War Stop Line in the Hoo Peninsula, part of the wider Hoo Peninsula study. The report states: "Second World War concrete Type 24 pillbox constructed on the western edge of Lodge Hill Wood near the north side of Lodge Hill Royal Naval Armaments Depot. It is located on Rough Shaw, a north west facing slope at the point where the anti-tank ditch meets the west side of Lodge Hill Wood. This is recorded on aerial photographs taken in 1944 and 1953 but has not been identified on later photographs. Its current condition is unknown." (1)
