The Biblioteca Nacional de Chile is the national library of Chile. It is located in Santiago, in a building completed in 1925, though its history reaches to the early nineteenth century before it was relocated to its current home.
Since its creation, the library had been a dependency of the Universidad de San Felipe and its successor, the Universidad de Chile, until it gained autonomy in 1852. In 1913, upon its 100th anniversary, the Biblioteca Nacional acquired the Monasterio de Santa Clara, located on the Alameda de las Delicias on present-day Cerro Santa Lucía. At the creation in 1929, the library was made into a dependency of the Dirección de Bibliotecas, Archivos y Museos.
The Biblioteca Nacional has an extensive and valuable collection of books and manuscripts. Several of these were acquired from or donated by their owners, making up an important national historical treasure.
