The Colosseum in Rome rarely needs any introduction. The building commands the area around the Roman Forum, east of the Palatine Hill and is an iconic symbol of Ancient Rome. It is oval in shape, 189 metres long, 156 metres wide and stands 50 metres high. It is the largest amphitheatre in the Roman world and could seat 50,000 people. It was built between 72 AD and 80 AD under the Emperor Vespasian to enhance the Emperor's popularity. This image shows entrances to the seating area looking across the Colosseum floor from another entrance and shows the skills of the builders through the triumph of brick vaulting.
