It is a elliptical buildings, and it is by far one of the greatest works of Roman engineering and architecture. It sits on a site that is just east of the Roman Forum. The Colosseum was built between 70 and 72 AD under the emperor Vespasian. It was not complete until 80 AD under the ruler Titus. There were also further modifications added during the next emperor’s reign. The Colosseum was originally built to seat about 50,000 spectators. At this time, it was used for games between gladiators and other public spectacles. The last recorded games at the Colosseum was in the 6th century AD. During the medieval era, the Colosseum was no longer used for entertainment events. Instead, it was left vacant until it became useful for religious and government purposes. It is truly a site you cannot miss.
