Ragusa (Sicilian: Rausa) is a city in southern Italy with 75,000 inhabitants. It is built on a wide limestone hill between two deep valleys, Cava San Leonardo and Cava Santa Domenica. Together with seven other cities in the Val di Noto, it is listed among the UNESCO World Heritage Sites. Its origins can be traced back to the 2nd millennium BC, when in its area there were several settlements of the ancient Sicels. an Italic tribe who inhabited eastern Sicily during the Iron Age. Their neighbours to the west were the Sicani. The Sicels gave Sicily the name it has held since antiquity, but they rapidly fused into the culture of Magna Graecia.
