The La Boca barrio, or neighborhood, in Buenos Aires, grew up on the bank of the Riachuelo, a narrow canal where meat packers and warehouses serviced the city. Italian immigrants found a home here, and their hastily erected tin houses formed the basis of the residential area.
Caminito, a pedestrian street named for the famous tango, leads visitors past mulit-hued houses and shops in what is now a tourist attraction and an artist's colony.
