For enthusiasts of Roman history, a remarkable discovery awaits just outside Cirencester, the biggest town in the Cotswolds. Here lie the impressive earthwork remains of one of Britain’s largest Roman amphitheatres, a grand structure dating back to the early 2nd century AD.
During the Roman era, Cirencester—then known as Corinium—was the second largest settlement in Britain after London. Its amphitheatre, built when the town thrived, could host up to 8,000 spectators, nearly matching Corinium’s entire population at the time. Originally a modest quarry that supplied stone for the town’s construction, the site evolved into a vast entertainment venue featuring tiered wooden seating supported by terraced drystone walls.
Distinctively oval in shape, the amphitheatre had entrances at both ends of its long axis, setting it apart from the circular designs found in places like Silchester and Dorchester. The arena floor was covered with sand and gravel and separated from the crowd by a barrier. Later modifications included small chambers near the entrances—one likely dedicated to Nemesis, the goddess honored across Roman amphitheatres.

After Roman rule ended in AD 408, Corinium declined rapidly as the military and economic support vanished. The amphitheatre’s function shifted dramatically; its gateways were narrowed and a defensive trench dug along its southern side in an attempt to fortify the town. Despite these efforts, the site fell to Saxon forces by AD 577 and remained unused for centuries.
Archaeological finds reveal that wooden structures once stood here in the 5th century, and during the Middle Ages, the local Abbot fenced off the area to use it as a rabbit warren. Its local name, “the Bull Ring,” suggests it may have hosted bull-baiting, perhaps echoing its original Roman entertainment roots.
Today, visitors can freely explore the amphitheatre’s substantial earth embankments and imagine the vibrant scenes of ancient spectacles. Located just a short walk from Cirencester’s centre, the site offers free parking nearby as well as convenient access to shops, toilets, and eateries. Dogs are welcome on leads, although some uneven terrain and a small staircase at the entrance mean the site is not fully wheelchair accessible.
This hidden Roman relic remains a striking testament to Britain’s rich ancient heritage and is well worth a visit for history lovers and curious travellers alike.
