An amphitheatre is a freestanding structure with a circular or oval shape, designed for public events and performances. It typically features tiered seating that allows large audiences to view activities such as plays, concerts, or sports. The design promotes good acoustics and visibility, making it an ideal venue for entertainment. Historically, amphitheatres were prominent in ancient Rome and Greece, where they hosted gladiatorial contests and theatrical performances. Famous examples include the Colosseum in Rome and the Theatre of Epidaurus in Greece. Today, modern amphitheatres continue to be popular for various cultural and recreational events.
