The most iconic of Rome’s ancient sites, the Colosseum is a 50,000-seat arena once used to stage spectacular battles between gladiators, slaves, prisoners and wild animals in front of roaring, bloodthirsty crowds. Today, just standing beneath its grandeur is enough to give anyone goose bumps.
Legend has it that tossing a coin into the Trevi Fountain ensures a return visit to Rome. Judging by the carpet of change in the basin, most tourists would be glad to have their wish come true.
