Ceramics with geometric decoration painted in black or red have been known for a quite long time for the Chalcolithic of the southern Iberian Peninsula, but the provenance and dating of this type of ceramics has been heavily debated. Now this type of pottery seems to be accepted as a highly appreciated local product, appearing not only in funerary contexts but also in settlements. The number of known items from western Andalusia, quite small in comparison to Eastern Andalusia, has now significantly increased, thanks to the rescue excavation undertaken prior to the construction of the new public library in the Chalcolithic mega-site of Valencina de la Concepción (Seville), where they appear in significant numbers and showing diversity of decorative motifs. We will present these ceramics, their context and chronology as well as the possible connections with the fragments excavated in the 1950s by M. Tarradell in the cave of Gar Cahal (Morocco).
