1999 Wide overgrown ditch, formerly an anti-tank ditch which during WW2 was dry and flat-bottomed, with cleanly cut vertical sides revetted with wooden hurdles. 2000 A wide overgrown ditch, which during WW2 was dry, flat-bottomed, and with vertical sides that were revetted with woven hurdles. The latter were beginning to rot and crumble by August 1944.
The ditch is located in line with, and between, known sections of the Outer London Line, and is therefore likely to be a surviving part of the anti-tank ditch that was not in-filled. (Information from Mr. W. B. Barr).
