It is one of the five Italian regions that have been granted some degree of domestic autonomy by special statute. Its official name is "Regione Autonoma della Sardegna" (Sardinian: "Regione Autònoma de Sardigna"; English: "Autonomous Region of Sardinia"). It is divided into four provinces and a metropolitan city. The capital of the region of Sardinia — and its largest city — is Cagliari. Sardinia's indigenous language and the other minority languages spoken on the island (Sassarese, Gallurese, Algherese Catalan and Ligurian Tabarchino) are officially recognized by the regional law as having "equal dignity" with Italian.
