Have you ever been to Rome? I see Rome as an open historical museum. Everywhere you walk, every street you take has an historical importance and evidence of a glorious past: the one of the Great Roman Empire. Beside the Colisseum, one of the oldest standing building is the Pantheon. FREE of charge! Make sure to go in there, go to the middle of it and look up: you will be amazed. Not spoilining it. You have to see it yourself!
