Make your own way to the Arch of Constantine to meet your guide for your walking tour.
Your entrance ticket allows you to skip the long lines and enter the Colosseum quickly. Hear from your guide how the Colosseum was developed centuries before the advent of modern engineering in AD 70-80, and how it once held as many as 80,000 spectators.
Just outside, you'll marvel at the Arch of Constantine and then continue to learn about the features of the Roman Forum archaeological site and Palatine Hill. Legend says that on the Palatine, Romulus and Remus were kept alive by a female wolf, thus giving Rome its name.
Your tour ends at the Colosseum where you can continue to explore the area on your own.
