The American Gladiators setting is an ARENA. It is a large, enclosed space used for public events such as sports, concerts, and theatrical performances. The term 'ARENA' is derived from the Latin word for sand, which was used to cover the floor of the original Roman amphitheaters. In modern times, arenas are typically large, multi-purpose buildings with seating for thousands of spectators. They are often used for professional sports, such as basketball, hockey, and football, as well as for concerts and other entertainment events.
