The site was occupied by the pre-Roman Britons, likely as part of an iron working industry.  It was continually occupied throughout the Roman era, and the scale of industrial activity increased over the period.  It is clear that there was a focus of settlement activity near Bromsash, but the area appears to some archaeologists to have contained dispersed centres of activity and settlement rather than a Roman town. Ariconiums only documented significance is as a station on Iter XIII of the Iter Britanniarum', with the single mention there being its only mention in classical history.
It seems to have been abandoned shortly after 360. Its sudden abandonment is consistent with a violent end, and may be related to the collapse of authority and widespread marauding at that time, as reported by Ammianus, a situation that lasted for almost a decade, and from which parts of Roman Britain never recovered. Evidence of later occupation of the site has not been found.
