Archaeological examinations of the site do not reveal why Cunetio deserved so much expenditure on upgrading its defences, an act that was a rare occurrence for inland Britannia at the time, when most Roman military engineering projects were focused on the Saxon Shore forts. Two theories have been suggested: first that the town was being converted into a Legionary fortress to re-establish Roman authority in this part of the province of Britannia. Second, that the improvement work was being orchestrated by an ambitious local British governor – the type of man who would, within a generation or so, be setting himself up as a war-lord or regional chieftain. Interpretation therefore swings between the Roman Empire re-establishing its authority after various rebellions and uprisings, or Roman authority breaking down.
