La Boca

La Boca is a neighborhood, or "barrio" of the Argentine capital, Buenos Aires. It retains a strong Italian flavour, with many of its early settlers being from the city of Genoa.
Geography.
As one of Buenos Aires's 48 barrios, La Boca is located in the city's south-east near its old port. The barrio of Barracas is to the west; San Telmo and Puerto Madero are to the north.
Etymology.
The neighborhood may derive its name from its location at 'La Boca' (the mouth) of the Riachuelo, as the Matanza River is usually called.
History.
In 1882, after a lengthy general strike, La Boca seceded from Argentina, and the rebels raised the Genoese flag, which was immediately torn down personally by then President Julio Argentino Roca.
Among sports fans, Boca is best known for being the home of the world-renowned football club Boca Juniors. The club plays their home matches in Estadio Alberto J. Armando, popularly known as "La Bombonera" (Spanish for "the bonbon box").
La Boca is a popular destination for tourists visiting Argentina, with its colourful houses and pedestrian street, the "Caminito", where tango artists perform and tango-related memorabilia is sold. Other attractions include the La Ribera theatre, many tango clubs and Italian taverns. The actual area visited by tourists is only a few blocks long and has been built up for tourism very actively over the last few years, with many market stalls and restaurants catering to tourists. Outside this tourist area, it is a fairly poor neighborhood that has had many regular occurrences of petty crimes reported.
It has also been a centre for radical politics, having elected the first socialist member of the Argentine Congress (Alfredo Palacios in 1935) and was home to many demonstrations during the crisis of 2001.
As of 2016, the health of over 1,000 La Boca citizens is threatened by the pollution of the Matanza-Riachuelo River (which contains high levels of arsenic and lead due to centuries of unstopped pollution).
