Naples rewards travelers who focus on its extraordinary density of history rather than trying to see everything. The Naples Cathedral (Duomo) and the ornate Sansevero Chapel showcase the city's baroque and artistic riches within a few blocks of each other, while a walk down Spaccanapoli threads through the lively historic center connecting them. For a change of scale, the Pompeii Archaeological Site preserves an entire Roman city frozen by Vesuvius, offering a level of ancient detail few destinations can match. Together these picks balance compact, walkable culture with a bigger day trip, making them the smartest priorities for a short stay.
