Naples. Under the shadow of  Vesuvius, Naples is best known for its medieval and Baroque architecture. With Pompeii on its doorstep and as many churches as Rome, there’s a lot to see in this city on the  Bay of Naples. Sip a glass of Lacryma Christi wine from the slopes of Vesuvius or shop on Via San Gregorio Armeno. Or simply relax with a Margherita pizza at one of the many piazza cafés.
