Understand how and why men had to fight and often die for the pleasure of onlookers. Above the arena floor, visit the upper levels where the people of Rome cheered and jeered those below who were torn apart by beast and blade. After a short break, explore the Dungeons of Carcer Tullianum (Mamertine Prison).
