In 647 AD (the year 27 of the Hegira), the first Muslim expedition to Africa took place. By 700 AD, the area had been conquered and converted to the Islamic faith. We know little of the early Islamic town, but by the tenth century the area outside of the fortress was once more filled with houses: on the site of the Roman baths over twelve of these were excavated, with large courtyards surrounded by long, thin, rooms.[38]
