Buenos Aires was founded on the shores of the Rio de la Plata in 1570 and was named after the patron saint of sailors for the good wind or buen aire.
The city remained a colonial backwater for 200 years while the Spanish concentrated their attentions on wealthier Peru. During this time Buenos Aires became a thriving centre for smuggling between South America and Europe.
Dissatisfaction with Spanish economic and political dominance escalated to boiling point and culminated in the revolution of May 1810 and finally to independence in 1816.
Its history since then has been dogged by military coups and political mismanagement; the consequences of which are growing disaffection with the government and widespread poverty, as is evident in the sprawling shantytowns on the city's outskirts.
This turbulent history has not managed to stifle the indomitable spirit of the Porteños whose passion, charm and vibrancy have forged this great city, a place in which the fire of Evita's soul and the allure of the tango endure.
La Boca ('the mouth') is the most colourful neighbourhood or barrio in Buenos Aires, and the original home of football legend Diego Maradona and the tango.
An assortment of brightly painted low houses made of wood and metal line the streets, including the famed main street Caminito, in this poor but happy area full of artisans, painters, street performers, cantinas and open-air tango shows.
The neighbourhood was originally settled by Italian immigrants, most of whom came to work in the docks. Today it is frequented by crowds of tourists who come to soak up the atmosphere.
