As the Eiffel Tower is to Paris, the silhouette of the Flavian Amphitheatre is to Rome. The largest structure left to us by Roman antiquity, the Colosseum still provides the model for sports arenas – present day football stadium design is clearly based on this oval Roman plan. The building was begun by Vespasian in AD 72, and after his son Titus enlarged it by adding the fourth story, it was inaugurated in the year AD 80 with a series of splendid games. The Colosseum was large enough for theatrical performances, festivals, circuses, or games, which the Imperial Court and high officials watched from the lowest level, aristocratic Roman families on the second, the populace on the third and fourth.
Beside the Colosseum stands the almost equally familiar Arch of Constantine, a triumphal arch erected by the Senate to honor the emperor as “liberator of the city and bringer of peace” after his victory in the battle of the Milvian Bridge in 312.
