The Colosseum

Rome's Colosseum was built in the first century A.D., centuries after the first Seven Wonders of the Ancient World came into vogue among Hellenistic travelers. Two thousand years later, though, the colossal amphitheater got its due when it joined the New 7 Wonders. Up to 50,000 people once flocked through its gates for gladiator contests and other events. Now in ruins, the Colosseum is the site of official Roman Catholic ceremonies and one of Rome’s biggest tourist attractions.
