Gladiators' places were typically ARENAS, which were large, open-air venues used for public events such as gladiator fights, chariot races, and theatrical performances. These ARENAS were usually oval or circular in shape and could hold thousands of spectators. They were often located near major cities and were built from stone, wood, or brick. The most famous example of an arena is the Colosseum in Rome, which was built in the 1st century AD.
