An amphitheatre is an open-air venue designed for performances, events, or gatherings. It typically features a circular or oval shape, with seats arranged in a tiered manner around a central area. This design allows for good visibility and acoustics, making it ideal for theatrical performances, concerts, and public speeches. Historically, amphitheatres were prominent in ancient Rome and Greece, where they hosted gladiatorial contests and other spectacles. Famous examples include the Colosseum in Rome and the Theatre of Epidaurus in Greece. Today, modern amphitheatres continue to be popular for entertainment and cultural events worldwide.
