Examples of architectures and household equipment made of clay, wood and stone during the Second Iron Age at the site of Quinta de Crestelos (Sabor River in the Duero valley, Northwest of the Iberian Peninsula) are presented. The archaeological excavations developed in this site between 2011 and 2014 allowed the identification of a model of catchment area unknown until now in the region, devoted to the exploitation of the lands close to the fluvial courses and with clear influences from the West Meseta. Finally, we reflect on the value of these raw materials as possible cultural and/or functional markers.
