The Roman Amphi Theater

As the Empire grew, most of its amphitheatres remained concentrated in the Latin-speaking western half, while in the East spectacles were mostly staged in other venues such as theatres or stadia. In the West, Amphitheatres were built as part of Romanization efforts by providing a focus for the Imperial cult, by private benefactors, or by the local government of colonies or provincial capitals as an attribute of Roman municipal status. A large number of modest arenas were built in Roman North Africa, where most of the architectural expertise was provided by the Roman military.
