The earliest Roman amphitheatres date from the middle of the first century BC, but most were built under Imperial rule, from the Augustan period (27 BC–14 AD) onwards. Imperial amphitheatres were built throughout the Roman empire; the largest could accommodate 40,000–60,000 spectators, and the most elaborate featured multi-storeyed, arcaded façades and were elaborately decorated with marble, stucco and statuary. After the end of gladiatorial games in the 5th century and of animal killings in the sixth, most amphitheatres fell into disrepair, and their materials were mined or recycled. Some were razed, and others converted into fortifications. A few continued as convenient open meeting places; in some of these, churches were sited.
Contemporary amphitheatres
A contemporary amphitheatre, the sense in which the word has come to be used now, is a curved, acoustically vibrant performance space, particularly one located outdoors. Contemporary amphitheatres often include standing structures, called bandshells, sometimes curved or bowl-shaped, both behind the stage and behind the audience, creating an area which echoes or amplifies sound, making the amphitheatre ideal for musical or theatrical performances. Most are semicircular in shape, so they should not properly be called amphitheatres. Notable modern amphitheatres include the Shoreline Amphitheatre and the Hollywood Bowl. The term "amphitheatre" is also used (incorrectly) for some indoor venues such as the Gibson Amphitheatre. The largest amphitheatre in the world is Bristol Motor Speedway in Bristol, Tennessee, with a seating capacity of 160,000.
