- Historical significance: The Arena Floor was the battleground where gladiators fought brutal duels, wild animals were unleashed, and grand spectacles entertained thousands of spectators.

- Dimensions: The Arena Floor spans 87m x 55m, covering the underground hypogeum.
- Materials used: Wood and sand (historically), with modern reconstructions using steel and wood to restore sections for visitors.
- Current use: A restricted-access area offering visitors a gladiator’s perspective of the Colosseum, providing unmatched views of its tiered seating and a deeper connection to its bloody past.
