Inauguration of the Colosseum

Emperor Titus inaugurates the Flavian Amphitheatre (the Colosseum) with an extravagant 100-day festival of gladiatorial combat, animal hunts, and mock naval battles. Built on the site of Nero's drained artificial lake, the arena is an engineering marvel: 50,000 seats, a retractable awning system, and an underground network of tunnels and elevators for staging elaborate spectacles. The Colosseum becomes the empire's most visible symbol of Roman power and public entertainment, and later tradition holds that Christian martyrs died on its sand.
