Rome is full of historic sites. It is said that a subway line started ten years ago has not been built yet. The reason is that every foot dug touches the remains of ancient Rome from 2700 years ago. Only by visiting on the spot can we deeply feel the unparalleled brilliance. Roman Forum and Palatine are the most worthwhile places to visit. Every inch of soil, every stone, every inscription (though I don't know Italian) tells the story of history.
