The original 1990 law defined as metropolitan cities the comuni of Turin, Milan, Venice, Genoa, Bologna, Florence, Rome, Bari, Naples and their respective hinterlands, reserving the autonomous regions the right to individuate metropolitan areas in their territory.[1] In 2009, amendments added Reggio Calabria to the list.[2] The metropolitan areas defined by the autonomous regions were: Cagliari in Sardinia; Catania, Messina and Palermo in Sicily.
