Built around 70 AD and located east of the ancient city, it was intended for dramatic performances. With its 148m diameter, it appears as the largest in the Roman world, able to accommodate 20,000 spectators. The theater was built in the classical style, with terraces arranged in three semicircular rows, cut by staircases, on the natural slope of the land. An imposing wall closed the theater behind the stage, supposedly 30m high.

At the exit of Autun

No one, not even scientists, knew the exact function of this temple or the deity that was celebrated there.
