Overview: The Roman Colosseum, completed in 80 A.D., was a showcase of gladiatorial contests, wild beast hunts, public executions and variety shows. The Colosseum is brought to life with a virtual reality simulation, based on a detailed study of the archaeological evidence. The rules of the gladiatorial games are examined and modern-day gladiators recreate the legendary battles. Scientists try to determine the truth behind the legend of the Naumachia, a mock naval battle which involved the flooding of the entire arena.
