Did you know that the Colosseum was designed to hold 50,000 spectators and it had approximately 80 entrances so crowds could arrive and leave easily? Now that's pretty clever.
Did you know that the facade of 3 tiers of arches and an attic story is about 48.5 m (158 ft) tall - roughly equivalent to a 12-15 story building?
Did you know it's not in my "must stop" list? I know, I know. It's one of those decisions that must be made. In a short time frame to visit a place, one has to hit the spots. First one must identify the spots. In my case, I had one - Vatican - where I planned to see St. Peter's Basilica and of course where I will meet my high school girl friend. I was very excited to be in Rome because of her. We haven't seen each other in ages.
