Gravina in Puglia is a town and commune of the Metropolitan City of Bari in the Puglia (Apulia) region of Southern Italy. The name gravina derives from the Latin grava or from the messapic graba, with the meaning of rock, shaft and erosion of bank river. Alternatively, when the emperor Frederick II went to Gravina, because of the large extension of the lands and for the presence of wheat, he decided to give to it the motto Grana dat et vina (‘It offers wheat and wine’). Gravina is the home of the Alta Murgia National Park.
