Transport yourself back to 80 AD and pretend you're in the presence of gladiators, wild animals, and emperors as the warm Italian sun beats down upon your face. The massive amphitheatre, located in Rome, is a sight to behold. One of the Seven Wonders of the World, the man-made arena can hold a crowd of over 50,000 people and miraculously, is still standing today. Take a guided tour or venture on your own, but while on the premises, be sure to visit the tunnels that the gladiators once used to prepare for spars, and where caged lions and tigers waited anxiously for their fights. In the same archaeological area exists the Roman Forum and Palatine Hill. Both offer breathtaking views, mind-blowing ancient ruins, and a once-in-a-lifetime lesson in history.
