Informal barrio names
The name Barrio Sur was used in the past to encompass the southern neighborhoods. This name has mostly fallen out of use, but survives in the lyrics of the tango Sur, which refer to specific places in Nueva Pompeya and Boedo, and in the short story "The South" by Jorge Luis Borges, where the conventional wisdom is recalled that "the South begins when crossing Rivadavia Avenue".
Abasto is sometimes used to refer to the zone around the Abasto market (now a shopping mall), many times in association with the life of Carlos Gardel. It encompasses north-western Balvanera and north-eastern Almagro.
Catalinas Norte is the high-rise district next to Retiro transportation center and to the financial district, while Catalinas Sur is used (quite rarely) for the lowlands south of San Telmo (notably the area around Cosme Argerich hospital and at the bottom of Parque Lezama).
Palermo is the largest barrio by area and has several informal subdivisions; Palermo Viejo is the name usually given to the area between Coronel Diaz, Cordoba, Scalabrini Ortiz and Güemes; Palermo Chico and Barrio Parque the most upmarket part of Palermo is on Palermo's north-eastern edge, includes the National Museum of Decorative Arts and MALBA, the Museum of Latin American Art and many of the wealthy and famous old homes some now used as Ambassador's residences; Palermo Soho, the city's fashion district, refers to Plaza Julio Cortázar and its surroundings; Palermo Hollywood is a distinctive quarter located in the northern edge of the barrio where radio and TV stations, movie producers and workshops have settled in the late 1990s. Las Cañitas refers to a few blocks around the Campo Argentino de Polo, crowded with trendy bars, fancy restaurants and nightclubs. "Palermo Queens" is used sometimes to refer to the parts of Villa Crespo close to Palermo Viejo. Other than Palermo Viejo and Palermo Chico, these names are of recent vintage (1990s and later) and are related to the gentrification process that Palermo and its peripheral areas are undergoing.
Parque Centenario is sometimes used to refer to the area around Centenario park, at the limit of Almagro, Caballito, and Villa Crespo.
The southern parts of Flores were reclaimed from swampland, and the names Bajo Flores and Bañado de Flores are used for these areas.
Within Belgrano, there are Belgrano "C" and "R" (widely and incorrectly believed to signify "commercial" and "residential", respectively) and Bajo Belgrano ("Belgrano lowlands"), which since the late 1990s includes a small Chinatown.
A tango song named "Cien barrios porteños" (The 100 barrios of Buenos Aires), sung by Alberto Castillo, is sometimes invoked (informally) to support the claim that there are indeed a hundred neighbourhoods in the city. This number may be reached by including some suburbs in the tally.
