The hillside town of Matera, Italy is one of the oldest continuously inhabited cities in the world. And inside almost every building, there's a cave. See the story this Sunday. | CBS Sunday Morning

Matera is a city on a rocky outcrop in the region of Basilicata, in southern Italy. It includes the Sassi area, a complex of cave dwellings carved into the mountainside. Evacuated in 1952 due to poor living conditions, the Sassi now houses museums like the Casa Grotta di Vico Solitario, with period furniture and artisan tools. Nearby rock churches include St. Lucia alle Malve, with 13th-century frescoes. It's one of Italy's most unique destinations and designated UNESCO World Heritage Site since
