The metropolitan area () is a type of administrative division in Portugal. Since the 2013 local government reform, there are two metropolitan areas: Lisbon and Porto. The metropolitan areas of Lisbon and Porto were created in 1991. A law passed in 2003 supported the creation of more metropolitan areas, under the conditions that they consisted of at least nine municipalities (concelhos) and had at least 350,000 inhabitants. Several metropolitan areas were created under this law (Algarve, Aveiro, Coimbra, Minho and Viseu),
