Romantic Naples, two hours south of Rome, is the largest city in southern Italy. It has some of the world's best opera and theatre houses and is often called an open-air museum, due to its many historic statues and monuments. Join families on the promenade as the sun sets on the Bay of Naples. View finds from Pompeii and Herculaneum, destroyed by Mount Vesuvius in 79 A.D., at the Museo Archeologico Nazionale or revel in the art and architecture of Museo Cappella Sansevero, built in the late 1500s.

Though dwarfed by nearby Naples, Caserta punches above its weight when it comes to world-class landmarks. Its roll call of sights include the colossal Royal Palace of Caserta, the Aqueduct of Vanvitelli, and San Leucio Complex; all three of which are UNESCO World Heritage sites.

Kas may be known as Turkey's premier scuba diving destination, but with its ancient ruins, oceanside restaurants, and bougainvillea-covered houses boasting Ottoman-style balconies, the seaside town offers more than just underwater pursuits.
