I think that Rome, the "Eternal City" is one of the most popular tourist destinations in the world. It was once the capital of western civilization, Rome has incredible antiquities, gorgeous piazzas, stunning fountains, great food, and a wonderful ambiance. The saying "All roads lead to Rome" was a truism during the Roman Empire and the city displays its heritage in a spectacular fashion. Rome is a fantastic destination; you will run out of time before you run out of worthwhile things to see and do. Do you know other eternal cities in the world like Rome?
