The Roman Colosseum is a treasure trove of historical facts for archeologists who continue to make discoveries even after 2,000 years. Since January 2021, a study has been conducted to clear around 70 meters of ancient drains and sewers beneath the iconic construction.

The Colosseum was the biggest amphitheater in the Roman Empire, the first super-stadium in history, famous for hosting gladiatorial fights and other public spectacles in front of crowds of tens of thousands. It fell into disuse around 523 AD.
