Buenos Aires | Argentina

Buenos Aires serves as the federal capital and primary cultural engine of Argentina. It is situated on the western shore of the Río de la Plata, functioning as a major global city often characterized by its European-influenced architecture and high density of theaters.

Historical Timeline

Founded twice by the Spanish (1536 and 1580), the city became the capital of the Viceroyalty of the Río de la Plata in 1776. The "Golden Age" (1880–1930) saw massive wealth from agricultural exports, financing the construction of Parisian-style boulevards and landmarks. In modern history, the 2001 economic crisis and the 2023-2024 hyperinflationary period have redefined the city's economic landscape, shifting it toward a tech and service-oriented hub despite fiscal volatility.

Demographics & Population

The metropolitan area (Greater Buenos Aires) has a population of approximately 15.6 million. The demographic is predominantly of European descent (Italian and Spanish), with significant recent migration from neighboring South American countries. Residents, known as Porteños, are characterized by a distinct "Rioplatense" Spanish dialect and a sophisticated, albeit often cynical, urban outlook.

Facts & Legends
