The Espai Mercè Sala, located in Diagonal metro station, hosts this exhibition focused on heritage photography. The route features twenty-five large-format black-and-white prints, drawn from a collection of more than one hundred glass negatives recovered from the premises of Transports Metropolitans de Barcelona. These pieces document different moments in the city's urban history linked to the local transport network and were produced by professional photographers from Barcelona's studios of the period.

In addition to the material on display in the galleries, the visit includes the screening of an explanatory video on the technical process used to recover the original glass plates. Several works also feature QR codes that allow visitors to download the images directly. The exhibition is aimed at anyone interested in the graphic history of Barcelona and the city's archive collections.
