The Colosseum in Rome is probably one of the most famous relics in the world and tells us of a time with the Roman Empire was a super power. It is the largest amphitheater in the world and was complete 80AD under the emperor Titus.
Back in the day it could seat up to 80.000 spectators and was used for a whole array of spectacular events, such as mock sea battles (they could flood the arena), gladiatorial contests and animal hunts. However against popular belief they didn’t hold any chariot races in the Coloseum, or Flavian Amphitheater as it is also know, and whether of not Christians were martyred in it is disputed.
Today the Colosseum, like the entire historic center of Rome, is listed as a world heritage site and is listed as one of the New7Wonders of the World.
