Mapping changes in late prehistoric landscapes: a case study in the Northeastern Iberian Peninsula

The temporal span of the Late Bronze Age and the Early Iron Age (1300-550) saw the emergence of intense interconnectivity in the Mediterranean sea. The development of colonial trade dramatically increased cultural exchange along its coasts as can be observed in archaeological evidence. These large scale processes had an impact at all scales and territories close to the main trade routes. However, the process was extremely diverse in its forms. This work presents a case study focused on two adjacent areas in the coast of the NE Iberian Peninsula. Spatial analysis has been carried out to explore the trajectories of settlement location dynamics during the whole period. Basic geographic variables, mobility and distance to trade routes have been explored to identify key differences over periods and areas. Results indicate that the factors guiding settlements location varied between the two zones. Moreover, one of the areas was radically influenced by trade routes in the Early Iron Age while the other did not seem to be affected by this external factor. The interpretation of these analyses suggests that the rise in connectivity was not homogeneous over the Western Mediterranean, but in the regions where it took place this factor was decisive to explain their historical trajectories.
