Abstract This article presents the results of the geoarchaeological study of earthen building materials used in a Tartessic public building at Casas del Turuñuelo. The construction dates back to the fifth century BCE and is one of the monumental buildings of Tartessic culture, characterized by its complex architecture, prestige goods, and intentional destruction after a feast and animal sacrifice. We applied an integrated methodology combining macro and micro approaches to investigate earthen construction processes, such as techniques, labour organization, workers’ specialization, and environmental exploitation. The sample mainly consists of mudbricks, but we also include other forms of earthen materials such as mud plasters, mud mortars, and geological soils for comparison. In total, 64 samples from different building parts were studied through X-ray fluorescence, X-ray diffraction, thin-section petrography, and CHN analyses. The results reveal that the workforce involved in the construction process used different resources and presented different skill levels, but was centrally planned and organized. This study reflects on the communities’ knowledge of the environment, the logistic effort and technical skill employed in the building process, and the existence of strong political structures capable of managing the erection of the complex Tartessic buildings. |
