World's Most-Visited Ancient Ruins
Annual Visitors: 6.9 million
When completed in A.D. 80, the arena held 50,000 spectators who watched mythology-based dramas and reenactments of land and sea battles as well as executions, fights-to-the-death among gladiators, and the ghastly slaughter of wild animals. The underground pits where those gladiators awaited their demise were opened to visitors in 2010 along with the 110-foot-high upper ring of seats, which offer panoramic views of the Eternal City.
