Collosseum

Colosseum, also called Flavian Amphitheatre, a giant amphitheater built in Rome under the Flavian emperors. Construction of the Colosseum was begun sometime between 70 and 72 CE during the reign of Vespasian.
The structure is depicted as God's Arena, where thousands of hand-to-hand combats between gladiators, of contests between men and animals, and of many larger combats, went on wreaking battles and brawls, including mock naval engagements
Being damaged by lightning and earthquakes in medieval times and, even more severely, by vandalism, all the marble seats, and decorative materials disappeared, as the site was treated as little more than a quarry for more than 1,000 years. Preservation of the Colosseum began in the earliest days of the 19th century, with notable efforts and a restoration project was undertaken in the 1990s. It has long been one of Rome’s major tourist attractions, receiving close to seven million visitors annually.
