Naples in Italy, an ancient port on the Mediterranean sea. With just short of a million citizens, is the third most populous municipality. Metropolitan Naples is Italy's second most populous metropolitan area. 

Naples represents one of the oldest continuously-inhabited cities in the world and a UNESCO World Heritage site with an unmatched heritage as a place of exchange between cultures. This is reflected in the city's structure and monuments, which are a mixture of Greek, Roman, Norman, Angevin, Spanish and French architecture. The UNESCO evaluation committee described Naples' historic centre – the largest in Europe – as being "of exceptional value", and went on to say that Naples' setting on its Bay "gives it an outstanding universal value which has had a profound influence". But Italians have known these things for centuries: The view of Naples from the sea is so beautiful that a traditional Italian saying states that once you've seen it, you can die.

As a testimony to its extraordinary history, the Naples region hosts an unparalleled concentration of UNESCO World Heritage sites: the Center of Naples itself; the Roman archaeological sites of Pompeii, Herculaneum, Cumae, Pozzuoli, Oplontis and Stabiae; the Royal Palace of Caserta; the royal site of San Leucio and the Aqueduct of Vanvitelli. It is close to Vesuvius, the only active volcano on the European continent and a UNESCO Biosphere Reserve. Paestum's Greek temples and the Amalfi Coast are possible day trips, as are the islands of Capri, Ischia and Procida in the Bay of Naples.
