The Historical Archive of Barcelona is a century-old archival and cultural institution dedicated to preserving the city's documentary heritage and promoting historical research and dissemination.

It is responsible for the custody, processing, and dissemination of documents generated or received by the city’s administration from the establishment of Barcelona’s municipal regime in the mid-13th century to the liberal revolution of the mid-19th century.

Around this rich initial core, other archival, bibliographic, and press collections have been added, all considered valuable for understanding the city’s history.

The wealth and diversity of its holdings have made it a reference center, not only in Barcelona but throughout the country, with international recognition due to the significance of the preserved materials.
