The Colosseum in Rome was first used in A.D. 80. In Roman times, it was called the Flavian Amphitheater and held 50,000 spectators. The name "Colosseum" was introduce in medieval times and referred to a giant statue of Nero that stood nearby. The outer walls have three levels of arches with columns topped by Ionic capitals at the lower level and Doric and Corinthian at the top. The 80 entrance/exit arches, known as vomitoria, allowed spectators easy access and the ability to clear the building in minutes.
