45. The Colosseum
The Colosseum in Rome, the largest Roman amphitheatre, was built between 70 and 80 AD. It could seat more than 50,000 spectators. Its inauguration gave rise to spectacular games lasting a hundred days, during which 5,000 wild animals and 2,000 gladiators were killed.

Mais aussi un symbole terrible de la brutalité de Rome. Financé par le pillage de Jérusalem, et comme dit, utilisé pour montrer des spectacles tragiques.
