Gran Buenos Aires

Also known as Buenos Aires Metropolitan Area, Área Metropolitana de Buenos Aires, AMBA

Greater Buenos Aires, also known as the Buenos Aires Metropolitan Area, refers to the urban agglomeration comprising the Autonomous City of Buenos Aires (CABA), and the adjacent 24 partidos (counties) in the Province of Buenos Aires. Thus, it does not constitute a single administrative unit. The conurbation spreads south, west and north of Buenos Aires city. To the east, the River Plate serves as a natural boundary.
