If you like photography, and you find yourself walking around Parc de la Ciutadella, do not forget to visit the Arxiu Fotogràfic de Barcelona (Photographic Archive of Barcelona).
Created in 1931, contains photographs of the Catalan capital, its people and its surroundings from 1844 until nowadays, and accumulates more than two and a half million photographs!
The headquarters is in the old convent of Sant Agustí Vell where you will find a photographic exhibition that changes a couple of times a year. The one that they have currently —January 2017— is about Humberto Rivas, an Argentinean photographer who arrived at Barcelona in the 50s and never left. The exhibition is called Huellas and consists of a total of 53 photographs where Humberto wanted to capture the sequels left by the Spanish Civil War.
On AFB’s website, you will also find a very small representation of the photos they have in their gallery. And if you want more, you can always go to the reference room, where you can ask for more specific kinds of photos.
