The ColosseumAlthough the name originally didn't refer to the structure itself, that's what it is: a colossus. It is huge! It is the largest amphitheater ever built and for many the prime symbol of Imperial Rome. Imagine the atmosphere of an audience of up to 80,000 people cheering for their favorite gladiator or for the emperor in a theatrical, reenacted battle.
If you walk down Via dei Fori Imperiali, you will already not know what to gaze at first: Remnants of a glorious past to your left and right. The Colosseum is visible from afar and it's easy to feel the excitement of a crowd heading towards the building for fun and distraction. "Bread and games" is what people need, they say.
Walk around the building to experience its dimensions. Once inside, you still see the necessary infrastructure of the old Rome's main entertainment facility. The underground quarters of gladiators and animals, different kinds of seating, and the foundations of supportive technology. In the early days it was even filled with water for the recreation of sea battles.
Don't forget that the Colosseum wasn't a fun place for everyone. It was a place of torture and death for perceived enemies of the Emperor, let alone the gladiators themselves. Tens of thousands of animals were killed for joy here as well. Today, the Colosseum also serves as a symbol of the international campaign against capital punishment.
The place supported an industry once, remains of adjacent buildings attest to that: a school for gladiators, a clinic, and a place that dealt with the dead.
