Life in Ancient Rome was pretty tough. And when the ancients needed entertainment, they got it in epic proportions at the Colosseum. Finished in 80 AD, it's the largest amphitheater ever built - it could hold up to 80,000 cheering spectators. They came to watch animal hunts, the recreation of famous battles and, of course, gladiators battling lions (and each other).
Today the Colosseum is a magnificent ruin. To quote Lord Byron, it is, "A ruin,—yet what ruin!" Enter and you can explore its vast interior, gaze up at the raked seating where the Roman masses sat, and look down on the floor area where the famous battles and hunts took place. Underneath the floor, there was a complicated system of hoists, ramps and trapdoors, allowing for beasts, men, and scenery to be raised into the arena.
