Attached to SW corner is another approx 20m length of coped brick wall which extends approx 20m to south. HISTORY: part of the E perimeter wall including the South Tower House and Gatehouse (qqv), built during the early C18 expansion of the Dockyard. The wall originally surrounded the yard with towers at the corners, each with pairs of oculi to each external face and a crenellated parapet. The remaining parts of the wall demonstrate the need for the protection of the Yard, before the mid C18 construction of the Chatham Lines, and define the extent of the early C18 dockyard -one of the largest factory sites of its date in the world.
