“An Iron Age hilltop enclosure with associated field system, plus an 18th century commemorative pyramid on a mound, known as Farley Mount, suggested to be a Bronze Age round barrow (ALK 7418/77)“. This photograph is from 1924, so all of these ditches which are visible today from the air, though somewhat diminished, predate the WW2 anti-aircraft guns which were somewhere nearby.
