Biblioteca Popular del Paraná, Public library in Paraná, Argentina

Biblioteca Popular del Paraná is a public library in Paraná with spaces designed for different activities, including multiple reading areas and study zones for visitors. The building at Buenos Aires Street 256 provides room for people to research, study, or simply read books in a structured setting.

Founded on 1 March 1873, the library was one of Argentina's first popular libraries, encouraged by the Commission for Popular Libraries created under President Domingo Faustino Sarmiento in 1870. After moving between rented rooms, it bought land on Buenos Aires Street with a public collection; the foundation stone was laid on 25 May 1908 and the building opened on 27 May 1910. It was declared a National Historical Monument on 28 June 2006.

Since 2010 the library has held an annual literary contest marking the centenary of its 1910 building. It is divided into three categories: adults from 18, adolescents aged 14 to 17, and pre-adolescents aged 10 to 13. Entries grew from 136 in the first edition to 2,622 in 2020.

The library occupies the building on Buenos Aires Street that was inaugurated in 1910, on the same block where it has stood since the early 20th century. The main reading rooms are on the ground floor, and the entrance is reached directly from the street. The building is a National Historical Monument, so some areas may be closed during restoration work; ask at the desk which rooms can be visited.

The building received National Historical Monument status in 2006, displaying noteworthy architectural design from its era. This heritage designation makes it a valuable example of how historical educational buildings have been preserved in the region.
