Our guide gave us some fascinating history of both the building (and network of hallways and rooms) and the life and times of a gladiator. Coupling both was a fantastic mixture of information that brought the Colosseum to life. Now when I look at the building, it brings up many images from how the gladiators fought as well the as political reasons for building such a facility in the first place. Go in September and make sure to get a "skip the line" ticket. It took all of 5 min to get in from the time we arrived. Without such a ticket, we were told it was a 3 hr wait in line to get tickets and enter.
