The first humans to settle in this area of what is now southern Italy took up residence in natural caves along the walls of the ravine formed by the Gravina River. Beginning around 9,000 years ago and continuing into the 20th century, the caves were further carved and expanded by these human occupants into an elaborate settlement. It"s now called the Sassi di Matera, a pair of districts in the city of Matera, Italy.
