Italy has 51 UNESCO world heritage sites with 9 in southern Italy (as of 2014). Southern Italy's world heritage sites include city centers, palaces, caves, trulli, and archaeological sites. Cities and sites are listed in the order in which they were inscribed by UNESCO starting with the sassi of Matera in 1993. For more about southern Italy, see Top Places to Visit in Southern Italy.
Matera is an unusual town in the interior of the Basilicata region known for the sassi, a huge troglodyte settlement. The cave houses, dug out of the tufa, were inhabited from Paleolithic times until the 1950s. Today the cave houses have been revived and you can even stay in a Sassi hotel. There are also fascinating Rupestrian churches carved out of the ravine.

The historic center of Naples is packed with interesting narrow streets, churches, and outstanding monuments. Castel dell'Ovo, the oldest castle in Naples, sits in a beautiful position on the promontory. The Spaccanapoli district is a string of narrow, winding streets that's mainly a pedestrian zone in the historic center. There are many tiny and interesting shops. Via San Gregorio Armeno, one of the streets in the center, is known for its artisan workshops making nativity scenes.
