The earthworks are the remains of the second largest amphitheatre constructed in Roman Britain, serving the Roman city of Corinium Dobunnorum which at the time was second only to London in size and importance in the Roman province of Britannia.

The earthworks show evidence of tiered wooden seating for around 8000 people, placed upon stone terraces. There are two entrances, at the north east and south west sides of the structure. The banking reached a height of 25 feet from the bottom of the arena.

The site was abandoned when the Saxons captured the town in AD577 following the Battle of Deorham.
