The ditch and counterscarp on the eastern side of Dover Castle between Avranches to the Cliff established in the 1790’s and though they are on the probable line of the medieval defences none of the original work is now apparent.

Between Avranches and the cliff the outer defences incorporate two distinct sections of similar length with a distinct kink between them. The southern section towards the cliff is orientated north-to-south while beyond the kink the defences extend in a north-westerly direction. It has been speculated that this kink results from the outline of the Iron Age hill fort whose defences that are thought to underlie the later works. a wide terreplein above the wall for guns and in the northern half there are substantial earthworks protecting four expense magazines which may have been added in the 1850s. There are eight 19th-cent. Gun embrasures in this area, close to Ashford Flank. The northern part of the outer defences, though essentailly medieval in character between spur and avrances also incorporate C18th century work. The couterscarps, and second tall bank are likley contemporary with the the bastions created by Twiss in the 1790's. Summarised from sources (1-2)
