Southern Italy’s largest city, Naples is famous for its intoxicating mix of Old World charm and modern grit. This is one of the oldest cities in Europe, with enough art, architecture, and archeology to hold its own against other metropolitan cities. But it’s the wood-fired pizza that really brings the crowds. Naples’ historic centre (a UNESCO World Heritage site) offers plenty of attractions between pizzeria stops: Don’t miss the Chiesa di San Gregorio Armeno, a 16th-century Baroque masterpiece, and the Duomo, a Roman Catholic cathedral that broke ground in the 13th century. View objects from Pompeii at the Museo Archeologico Nazionale di Napoli or revel in the Rococo glory of Museo Cappella Sansevero, built in the late 1500s. End the day as locals do, taking a promenade as the sun sets over the Bay of Naples.
