Artistically, Rome is the most fascinating city in Europe. Even if everything about the city seems to be chaotic, try to keep your cool. The Romans still dream of ruling the world and every bus driver thinks he is Julius Caesar. Nothing you can do will make them change their minds.
The key to enjoying Rome is to relax and not to end up with terminal cultural indigestion. There are so many artistic masterpieces that you must be selective. Whether your preference is Emperors or Popes, you can spend a lifetime getting to grips with Rome’s history. Every building is an architectural palimpsest.
