As years passed the temple and the surrounding monuments were often undergoing reconstruction. As rich men would attempt to make a name for themselves and as styles and tastes changed the look of Aquae Sulis changed. In about three hundred AD the city underwent a major renovation. The temple, which was about 250 years old by then, was enclosed with in a new retaining wall and a new façade as added to the temple. The springs were enclosed with in a huge vaulted hall that greatly increased the majesty of the entire establishment. It became a "vast echoing grotto, green and dank."
There was another reconstruction in the late third century, early forth century. The enclosure had begun to crack underneath the pressure from the massive building, to resolve these three buttresses were added and hidden behind a new façade. To balance this another façade on the north side was added. This was the last addition to during the Roman occupation of Britain.
The economy of Roman Bath was much like that of a medieval city. The major difference however was that Bath possessed a shrine known throughout all of Europe. This brought throngs of pilgrims and with the pilgrims came wealth and prosperity. This is reflected in the wondrous architecture and intricate mosaics, which still can be seen today.
When Rome’s dominance of the island ceased the Roman veneer was stripped away from bath and what was left was a Germanic tribal society as there had been before. There was however a post-Roman twighlight for quite a while, the city passed into Norman hands and in 1088 the town was ravaged by a rebellion led by Robert de Mobray.
