The Colosseum is one of the most recognisable structures in the world. Built during the Flavian dynasty, between 70CE and 80CE – then known as the Flavian amphitheatre – it is the largest amphitheatre ever built and was modelled after the ancient Teatro Marcello. The Colosseum held around 65,000 spectators and was used for gladiator contests, public spectacles such as re-enactments of famous battles, theatrical productions, animal hunts and executions.
