Archaeological research on Late Prehistory (8th-1st millenniums BC) recognises, at various scales and in different periods, multiple traces of cultural unity in the northern interior of the Iberian Peninsula, which includes the interior of central and northern Portugal. However, the research tradition in both Portugal and Spain has conformed to the political-administrative border and has categorised the material data and created narratives in isolation, restricting the interpretative perspectives in Holocene Prehistory Such narratives, insofar as they structurally shape ways of thinking about the Past, have created discursive categories that  urge us to question and rethink. In this sense CITCEM’s research group “Territories and Landscape”, whose research in Late Prehistory takes places mainly in the interior north and centre of Portugal, has defined as one of its main objectives the hosting of this international conference. It aims to start a program of dialogue and develop research synergies that erode the political border and contribute to the integration of this region in the wider space of the interior of the Iberian Peninsula. This dialogue will not in itself solve all the questions that arise from the traditional separation that for more than a century has conceptually divided the territories of the interior of the Iberian Peninsula, but it assumes itself as a platform for the creation of narratives that could be of greater benefit to current research.
