Plan of the Roman town c AD 150–400

By the late 2nd century the town had grown beyond the area of the old fortress. Around the year AD 180 a considerably larger defensive circuit was laid out, following the natural defences of the site and therefore irregular in plan. Within this area stone buildings steadily replaced the older timber ones. Some of the streets of the earlier Roman town were extended or changed to serve this larger area, but it is far from certain that a regular grid of streets covered the entire walled area.
