In the central Recoleta neighborhood of Buenos Aires, in a large lot between Austria Street, Agüero Street, and Del Libertador Avenue, stands the current building of the Mariano Moreno National Library, designed by architects Clorindo Testa, Francisco Bullrich, and Alicia Cazzaniga.
Built on the basis of the project that won first prize in a national competition in 1961, and completed in the early 1990s, it has become a landmark of modern Argentine architecture and an example of the variant of 20th century expressionism known as "brutalism".
