The spectacular physical presence of the rock engravings of the International Tagus raised, in the 1970s, the need to explain the symbolic expressions of a population that until then had been described as virtually inexistent and, as a matter of course, of little importance to the cultural panorama of Iberian Late Prehistory. This volume gathers together the research effort of the teams that over the past 25 years have developed archaeological interventions in the central area of the International Tagus.
