The Geonosian Arenas, built by the Confederacy of Independent Systems during the era of the Clone Wars, functioned as Monuments. These structures, erected by Geonosian laborers, each required a substantial investment of 3000 units of carbon, ore, and nova crystals. The design of the Arenas mirrored that of the Petranaki arena located on Geonosis, a site that marked the initial flashpoint of the Clone Wars conflict.
The Geonosian Arenas are featured in Star Wars: Galactic Battlegrounds: Clone Campaigns, the expansion pack for the 2002 video game. Within the game's multiplayer mode, players have the ability to construct monuments, including this very one. Successfully defending such a monument for a duration of 200 in-game "days" results in a scenario victory.
