The Coliseum is currently in a state of ruin (or almost), but remains a symbol of Rome Modern and will probably part of your visit to the Italian capital. The Colosseum (Colosseo in Italian) is a great oval amphitheater (like Nimes Arena) located in the center of the city of Rome, the largest ever built in the Roman Empire. It is one of the greatest works of Roman architecture and engineering.
Its construction, just east of the Roman Forum, started under Emperor Vespasian, and was completed under Titus.

"The Flavian Amphitheatre name derives from the surname (Flavii people) of the two emperors Vespasian and Titus.
Able to accommodate between 50,000 and 75,000 spectators, the Colosseum was used for venationes (wild animal fights), the munera (gladiator fights) and public spectacles such as executions of death row, re-enactments famous battles and dramas based on Roman mythology. "
