An amphitheatre is a large, open-air venue designed for performances and events. These structures have a circular or oval shape, allowing audiences to enjoy shows from all angles. Historically, amphitheatres were used for various activities, including gladiator contests and theatrical performances in ancient Rome and Greece. Today, modern amphitheatres continue to host concerts, festivals, and other entertainment events. They are often built in scenic locations, enhancing the experience for attendees. Famous examples include the Colosseum in Rome and the Hollywood Bowl in California, showcasing the enduring appeal of these architectural marvels.
