The Colosseum, also known as the Flavian Amphitheatre, is a testament to the architectural ingenuity of ancient Rome. Constructed from travertine limestone, volcanic rock, and concrete, it's the largest amphitheatre ever built, reflecting the grandeur of the Roman Empire. It was capable of seating 50,000 to 80,000 spectators who enjoyed a variety of public spectacles, including gladiator contests, animal hunts, and dramas. Despite the damage inflicted by earthquakes and stone-robbers over the centuries, it remains a symbol of Rome's imperial might and a center of cultural heritage.
