A short length of zigzag trench, representing a First World War practice trench or a Second World War air raid shelter or slit trench, visible as earthworks on aerial photographs and mapped as part of the English Heritage: Hoo Peninsula Landscape Project. The site lies within an area described, on a War Department map of Lodge Hill field defences, 1914-16, as part of the "New field works ground". It is adjacent to the Beacon Hill First World War anti aircraft battery and the First World War pillbox or war shelter on top of the Post Medieval beacon mound .The trench also lies immediately to the south of a Second World War military camp, and may have been used as an air raid shelter for that installation.
