Answer:
Only a small part of the full structure survived, because a lot of the stone was stolen and so the whole structure was not recorded.
But there is some stuff we know:
- The exterior walls were four stories high, and the first three stories were adorned with half-columns illustrating the three classic architectural styles (Doric, Ionic, and Corinthian).
- Underground mazes, underground structures, corridors, ramps, animal pens and rooms for prisoners, we all exposed due to the broken floor.
- The top story of the Colosseum was equipped with posts to which were attached a huge awning that would shield the spectators from the hot sun.
