The classic symbol of ancient Rome, the Colosseum was built in around 70 A.D. The Roman Colosseum was something we very much looked forward to seeing and we really enjoyed it, both inside and out. We learned on our tour that parts of the Colosseum have been rebuilt after crumbling - to support the rest and keep it from collapsing. After finding that out, it's easy to see which parts are newer, particularly the angled parts in front. The name "Colosseum" came from the word "colossal" and it could accomodate over 50,000 people.
