Library of the National Congress of Argentina, National library and parliamentary archive in Congressional District, Buenos Aires, Argentina.
The Library of the National Congress of Argentina is a parliamentary library and legislative archive in Buenos Aires, holding legal texts, government publications, and records from the country's congressional history. Its reading rooms and collection spaces occupy several floors of a building adjacent to the National Congress.
The library was founded in 1859, growing alongside the construction of the National Congress building, which took several decades to complete. It opened its main sections to the public in the early 20th century.
The library shows how Argentina documents its laws and government decisions through written records. Visitors can see in the exhibition spaces how legislative work has evolved over time.
A photo ID is required to enter the building, so it is worth keeping one at hand before joining a visit. Guided tours are available in Spanish and English for those who want a more structured way to explore the space.
The library's first collection was about 620 volumes that had belonged to Marshal Andrés de Santa Cruz, bought after Law No. 212 was passed on 23 August 1859 under President Justo José de Urquiza. The purchase had been urged in 1856 by Mendoza deputy Lucas González.
