Part of a Second World War anti tank ditch, constructed in 1940 across the Hoo peninsula from the north bank of the Medway near Hoo St Werburgh to the south bank of the Thames at Higham Creek (Monument 1542577). The ditch across Hoo was part of the system of GHQ Stop Lines designed to halt or delay the advance of a German invasion force landing in southern and south eastern England. The section described in this record ran north from the lower slopes of Deangate Ridge towards Higham Marshes near Cliffe for a distance of 1466.3 metres. The southern part of this section of the anti tank ditch is visible as earthworks on aerial photographs taken in June 1942. The rest was photographed in 1944, when the ditch was out of use and being backfilled, with mounds of earth lying alongside the former ditch. The other parts of the Stop Line ditch, as well as the many pillboxes, gun emplacements and roadblocks that accompanied it, have been recorded separately. The whole anti tank ditch system on Hoo has been mapped from aerial photographs as part of the English Heritage: Hoo Peninsula Landscape Project.
