The underground underworld arena is circular, about 30 meters in diameter. Surrounded by a high metal fence, made of rusty steel and chains, which curves slightly inwards to discourage any attempt at escape. High above, a barbed wire net partially covers the top. Around the arena raised platforms were built with metal scaffolding offering a privileged view. These platforms are adorned with gas lamps, illuminating the arena and creating macabre shadows.
