Colosseum
"The Colosseum is the largest amphitheater ever built, constructed between 70-80 AD to hold 50,000-80,000 spectators for gladiatorial combat, animal hunts, and executions. The floor could be flooded for mock naval battles. It's Italy's most-visited monument and the defining symbol of ancient Rome's power."

The Backstory
After Rome's fall, it was quarried for building materials—marble was stripped for St. Peter's Basilica. The hypogeum (underground tunnels where gladiators and animals waited) only opened to tourists in 2010.
Local Secret
"Book the 'Full Experience' ticket online 2-4 weeks ahead—it includes underground and arena floor, far more interesting than standard tour. Go at 8am opening or late afternoon."
