Gravina in Puglia is an Italian municipality in the Southern Italian Province of Bari, site along a river of the same name in the Western Murgia geographical area of Apulia. It's the seat of Alta Murgia National Park.The word gravina comes from the Latin grava or from the messapic graba, with the meaning of rock, shaft and erosion of bank river. Other words that share the same root are grava, gravaglione and gravinelle. Instead, when the emperor Frederick II went to Gravina, because of the large extension of the lands and for the presence of wheat, decided to give to it the motto Grana dat et vina., or rather It offers wheat and wine.
