Earthen Architecture and Craft Practices of Early Iron Age Ramparts: Geoarchaeological Analysis of Villares de la Encarnacion, South-Eastern Iberia

The use of mudbricks in Early Iron Age ramparts is an uneven feature of defensive architecture on the Iberian Peninsula. The use of mudbricks as a building material has been linked to the arrival of Levantine building traditions with the Phoenicians, and its appearance among local societies varies between the eighth and sixth centuries BC according to the public or domestic nature of the structures. In this article, we present the geoarchaeological analyses of the mudbricks used in constructing one of the defensive towers or bastions at Villares de la Encarnacion (Caravaca de la Cruz, Spain). This site, endowed with two complex fortification lines and towers, is one of the main settlements for understanding the development of the Early Iron Age among the inland and mountain communities of the region. The analytical program includes wavelength dispersive X-ray fluorescence, CHN elemental analysis, and thin-section petrography and provides new data about soil procurement and manufacturing choices. These results highlight the technical and social complexity behind mudbrick constructions and the adoption of new earthen practices among Early Iron Age communities in order to build more imposing and elevated towers that might convey an image of the power and strength of these inland settlements.
