These photographs come from the the Photographic Archive of the Hiking Center of Catalonia, also known by its acronym AFCEC. The documentary collections that integrate the AFCEC come from donations and particular legacies. Nowadays it has more than 400,000 images. The AFCEC has become a general archive because of the diversity of its donations, so not everything is linked to the mountain. Both thematic and geographic location of the photographs are very varied (archeology, caving, nautical, aeronautics, cycling, boxing …).

The AFCEC contains an important historical legacy, that was recognized with the award of Honor Jaume I in 1981 and the Unesco medal in 1999, as it is a sample of the first initiatives of scientific studies in Catalonia, the so-called scientific hiking.
