Striking, colourful, smooth, rare: lithic resources and cultural choices in the architecture, sculpture and portable artefacts of the Palacio III tholos monument (Seville, Spain)

The investigation of the Iberian megalithic phenomenon has only recently begun to benefit from the expansion of the technical and scientific potential of modern archaeology. There are still very few Iberian megaliths for which high resolution scientific research has been carried out, providing detailed data on their design, uses and biographies. This paper presents the results of the multi-disciplinary study of the Palacio III tholos, part of a larger megalithic complex located in Almadén de la Plata (Seville). This study is based on a wide-spectrum methodology that integrates geoarchaeology, techno-morphological and functional analysis of portable material culture and graphic analysis, all combined within a meticulously contextual perspective. The results provide a wealth of data on how, through a series of carefully constructed cultural choices, this monument represents a true place of encounter between the locally available geological resources and other resources that were only accessible through contact with neighbouring communities. Whether in its raw state, finely carved in the form of engraved and painted sculptures or transformed into artefacts of high technical and personal value, the materiality of the stone in the Palacio III tholos acquires multiple cultural dimensions that only a modern scientific approach is able to reconstruct
