The Colosseum, which was originally named Flavian Amphitheater, is the most impressive building of the Roman Empire and the largest building of the era. It is also considered as the greatest work of Roman architecture and engineering.
The ordered beauty of the Colosseum is in stark contrast to the murderous encounters that took place within it. The Colosseum was used for gladiatorial contests and public spectacles such as animal hunts, mock sea battles, re-enactments of famous battles, executions and dramas.
During the inaugural games of the Colosseum in 80 CE held by Titus, some 9,000 wild animals were slaughtered.
