British settlement of the Roman Empire at Cirencester
Corinium Dobunnorum
Corinium Dobunnorum was the Romano-British settlement at Cirencester in the present-day English county of Gloucestershire.
Its 2nd-century walls enclosed the second-largest area of a city in Roman Britain. It was the tribal capital of the Dobunni and is usually thought to have been the capital of the Diocletian-era province of Britannia Prima.
