The Buenos Aires Underground (Spanish: Subterráneo de Buenos Aires), locally known as Subte (Spanish pronunciation: [ˈsuβte], from subterráneo – 'underground' or 'subterranean'), is a rapid transit system that serves the area of the city of Buenos Aires, Argentina. The first section of this network (Plaza de Mayo-Plaza Miserere) opened in 1913, making it the 13th subway in the world and the first underground railway in Latin America, the Southern Hemisphere, and the Spanish-speaking world, with the Madrid Metro opening five years later, in 1919. Currently, Buenos Aires is the only Argentine city with a metro system.
