A large, ancient Roman theater used for public events, such as gladiator contests and performances.
The Colosseum in Rome is one of the most famous landmarks in the world.
Colosseum comes from the Latin word "colossus" (meaning giant statue) and the suffix "-eum" (meaning place). The term originally referred to a large amphitheater in Rome, named after the nearby Colossus of Nero, a giant statue that stood close to it.
Imagine a giant statue ('colossus') standing in a grand place ('-eum') — that's how you can remember that a Colosseum is a large arena.
