The guide for this tour, Ilaria, was truly outstanding. She was clearly an expert in the history of the Forum, Palatine Hill, and the Colosseum. We spent a good deal of time in both the Forum and Palatine Hill prior to visiting the Colosseum, and she explained how Rome is kind of like a lasagna, layers upon layers of earth and history. She happily answered our questions and helped us understand what we were seeing. We have taken a similar tour in the past, and still learned new information; it was our teenager's first visit there, and she was fascinated and engaged for the entire time.
