Itria Valley (in Italian: Valle d'Itria) is an area located in Apulia region, in Southern Italy. Itria Valley spreads over Province of Bari, Province of Brindisi and Province of Taranto, and coincide with the lower part of Murgia upland (Low Murgia). The towns of Martina Franca, Locorotondo, Cisternino and Ceglie Messapica overlook Itria Valley. "Valley" is an inaccurate term, because Itria Valley has not the typical conformation of mountain area valleys: it is just a depression due to karstic phenomena.
