An amphitheater is an open-air venue designed for performances, events, or gatherings. It typically features a circular or oval shape with tiered seating that allows large audiences to view the action from various angles. The design helps amplify sound, making it easier for spectators to hear performances without modern technology. Historically, amphitheaters were used in ancient Rome and Greece for theatrical plays, gladiatorial contests, and public spectacles. Famous examples include the Colosseum in Rome and the Theater of Epidaurus in Greece. Today, modern amphitheaters continue to host concerts, festivals, and community events, blending history with contemporary entertainment.
