Petron Amphitheater (Quezon City)

 theatre, amphitheater

An amphitheatre is an open-air venue used for entertainment and performances.With large central performance spaces surrounded by ascending seating, and were commonly used for spectator. They were given this name because their shape resembled that of two theatres joined together.

More typically used for theatrical or concert performances and typically feature a more traditionally theatrical-style stage with the audience only on one side, usually at an arc of less than a semicircle; these compare more closely to the theatres of ancient Greece, and have been more commonly built throughout history as performance spaces. Amphitheatres are typically man-made, though there are also geological formations used in the same manner which are known as natural amphitheatres.
