Editing Buenos Aires (section)

== Cityscape and culture ==
Plaza de Mayo remains the historic centre of Buenos Aires. The Casa Rosada occupies its eastern side, while the surviving [[Buenos Aires Cabildo|Cabildo]] stands on the western side of the square. [[Avenida de Mayo]] runs west from the area toward the National Congress.

[[Avenida 9 de Julio]] crosses the central city. The [[Obelisk of Buenos Aires]] was inaugurated at its intersection with Avenida Corrientes in 1936. The [[Teatro Colón]], opened in 1908, is the city's principal opera house.

Buenos Aires was one of the main urban centres in which [[tango]] developed around the Río de la Plata during the late nineteenth century. The music and dance later became internationally associated with the city.
