Fundación Mapfre is a significant cultural institution in Spain, and KBr is its recently opened exhibition space in Barcelona. KBr is dedicated to exhibiting the works of some of the world's finest contemporary photographers.

The name KBr is derived from the chemical symbol for potassium bromide, which is a chemical compound used in the analogue photography development process. As a tribute to the origin of contemporary digital photography - analogue photography, the logo for the new brand cryptically evokes the periodic table of elements.
