The Roman wall stood to a height of 0.9m including footings, but it could be seen to change direction at this point. The NE side of the Roman tower survived as a stump of flint and mortar projecting out from the city wall. It clearly abutted the wall, and could be seen to be of later construction, added, presumably, in the 4th century. Elsewhere the tower had been badly robbed, leaving only the rubble-filled foundation-trench.
