3An underground world

While it is certain that a lot of what went on at the Colosseum was underhand and definitely dangerous, there is also a literal underground area of the Colosseum.

Known as the Hypogeum, it was a two-level subterranean network of tunnels with 32 animal pens. There were also 80 vertical shafts which allowed for instant access to the arena – these were used for shifting animals and scenery during shows.
