Rione
Some towns refer to neighborhoods within a comune as a rione (Italian:; pl.: rioni) or a contrada (pl.: contrade). The term originated from the administrative divisions of Rome, and is derived from the Latin word regio (pl.: regiones), 'region'. All currently extant rioni are located in Municipio I of Rome. The term has been adopted as a synonym of quartiere in the Italian comuni. Terzieri, quartieri, sestieri, rioni, and their analogues are usually no longer administrative divisions of these towns, but historical and traditional communities, seen especially in towns' annual Palio.
