The Roman Amphitheatre, also known as the Colosseum, is a large, oval-shaped structure built in ancient Rome around 70-80 AD. It was primarily used for public spectacles, including gladiatorial contests, animal hunts, and theatrical performances. The amphitheatre could hold tens of thousands of spectators, showcasing the architectural and engineering skills of the Romans. These structures were typically made of stone and concrete, featuring tiered seating to provide good views for all attendees. The design allowed for efficient crowd management and quick access to exits. Other notable examples include the Arena of Verona and the Amphitheatre of Pompeii.
