Buenos Aires

Aragonese archives record that Catalan missionaries and Jesuits arriving in Cagliari (Sardinia) under the Crown of Aragon, after its capture from the Pisans in 1324, established their headquarters on top of a hill that overlooked the city. The hill was known to them as Bonaira (or Bonaria in Sardinian), as it was free of the foul smell prevalent in the old city (the castle area), which was adjacent to swampland. During the siege of Cagliari, the Catalans built a sanctuary to the Virgin Mary on top of the hill. In 1335, King Alfonso the Gentle donated the church to the Mercedarians, who built an abbey that stands to this day. In the years after that, a story circulated, claiming that a statue of the Virgin Mary was retrieved from the sea after it miraculously calmed a storm in the Mediterranean Sea. The statue was placed in the abbey. …

In 1516, navigator and explorer Juan Díaz de Solís, navigating in the name of Spain, was the first European to reach the Río de la Plata. His expedition was cut short when he was killed during an attack by the native Charrúa tribe in what is now Uruguay. The city of Buenos Aires was first established as Ciudad de Nuestra Señora Santa María del Buen Ayre (literally "City of Our Lady Saint Mary of the Fair Winds") after Our Lady of Bonaria (Patroness Saint of Sardinia) on 2 February 1536 by a Spanish expedition led by Pedro de Mendoza. The settlement founded by Mendoza was located in what is today the San Telmo district of Buenos Aires, south of the city center. More attacks by the indigenous people forced the settlers away, and in 1542, the site was thusly abandoned. …

The city of Buenos Aires lies in the pampa region, with the exception of some areas such as the Buenos Aires Ecological Reserve, the Boca Juniors' "sports city", Jorge Newbery Airport, the Puerto Madero neighborhood and the main port itself; these were all built on reclaimed land along the coasts of the Rio de la Plata (the world's widest river). The region was formerly crossed by different streams and lagoons, some of which were refilled, and others tubed. Among the most important streams are the Maldonado, Vega, Medrano, Cildañez, and White. In 1908, as floods were damaging the city's infrastructure, many streams were channeled and rectified; furthermore, starting in 1919, most streams were enclosed. Most notably, the Maldonado was tubed in 1954; it currently runs below Juan B. Justo Avenue. …

As Buenos Aires is strongly influenced by European culture, the city is sometimes referred to as the "Paris of South America". With its scores of theaters and productions, the city has the busiest live theater industry in South America. In fact, every weekend, there are about 300 active theaters with plays, a number that places the city as 1st worldwide, more than either London, New York or Paris, cultural Meccas in themselves. The number of cultural festivals with more than 10 sites and five years of existence also places the city as 2nd worldwide, after Edinburgh. The Palacio Libertad, located in Buenos Aires, is the largest cultural center of Latin America, and the third worldwide. Buenos Aires is the home of the Teatro Colón, an internationally rated opera house. There are several symphony orchestras and choral societies. …

Buenos Aires is the financial, industrial, and commercial hub of Argentina. The economy in the city proper alone, measured by gross geographic product (adjusted for purchasing power), totaled US$102.7 billion (US$34,200 per capita) in 2020 and amounts to nearly a quarter of Argentina's as a whole. Metro Buenos Aires, according to one well-quoted study, constitutes the 13th largest economy among the world's cities in 2005. The Buenos Aires Human Development Index (0.889 in 2019) is likewise high by international standards. The city's services sector is diversified and well-developed by international standards, and accounts for 76 percent of its economy (compared to 59% for all of Argentina's). Advertising, in particular, plays a prominent role in the export of services at home and abroad. …
