In September 1948 The Canterbury Excavation Committee began work on a site 27.4m south west of the Riding Gate on the city wall. At this location the city wall had suffered bomb damage in 1942. Two trenches were dug, one across the bank inside the wall, the other (4.88m further south beyond the major damage) against the outer face of the wall. Theses were coded C XIII CW A and B.
The trenches revealed that the Roman wall stood to a height of 2.44m on footings 0.91m deep and that the bank was contemporary with it dated to the late third-century date. In the Medieval period the city wall fell into decay and a building with chalk walls and an earth floor was erected on the surface of the bank. Later the bank of the Medieval defences was piled on its demolished remains. Much restoration work was carried out in c. 1790, in connection with the new Riding Gate.
