Photo taken on Nov. 25, 2013 shows the ancient city of Matera in the southern region of Basilicata, Italy. The Sassi of Matera is the most outstanding, intact example of a troglodyte settlement in the mediterranean region, perfectly adapted to its terrain and ecosystem. The first inhabited zone dates from the Palaeolithic, while later settlements illustrate a number of significant stages in human history. The Sassi of Matera was listed as one of the UNESCO World Heritage Sites in 1993.(Xinhua/Zhang Jing) |
