The square fort was built at the intersection of two Roman roads, the Fosse Way and Durnovaria-Isca Dumnoniorum road, apparently in the 2nd century. Its ditch survives around much of the site. A civilian settlement soon grew up nearby, encouraged by the building of what has been interpreted as a large stone mansio for the provincial postal service. It was a centre for pottery production in the 3rd century and occupation continued until the end of the 4th.
