This impressive image of the interior of operating chamber no. 11 of Cardona’s potassium salt mines, 600 meters deep, show the scale of mining activity in the heart of Catalonia during the Franco regime. The human figure in the center of the photograph makes it possible to measure the space, as big as a football field, and shows the magnitude of the extraction work promoted by the “Uni\u00f3n Espa\u00f1ola de Explosivos” society. This graphic document is witness to an economic model based on the intensive exploitation of natural resources, which transformed the landscape and local life.
