The Roman Colosseum is a giant stone-and-concrete amphitheater in the center of Rome that was used for mass public entertainment in ancient times, especially gladiator fights and wild-animal shows. Today it is one of the most famous archaeological sites and tourist attractions in the world.

What the Colosseum Is

  • The Colosseum (also called the Flavian Amphitheatre) is an oval arena built under the Flavian emperors Vespasian, Titus, and Domitian in the 1st century CE.

  • Its exterior shows stacked decorative orders (Doric/Tuscan, Ionic, Corinthian) and originally featured statues and awnings (the velarium) to shade spectators.

The Colosseum Today

  • After the fall of the Western Roman Empire, it was damaged by earthquakes, used as a fortress, and quarried for stone before later preservation efforts began.
