The Carambolo Treasure is an assemblage of gold items of the first millennium BCE, whose origin has for about 50 years been the epicentre of a heated debate. New chemical and isotopic analyses, carried out by the UPV/EHU’s Geochronology and Isotopic Geochemistry Service—Ibercron and commissioned by the University of Huelva and the Archaeological Museum of Seville, suggest that the source of the gold is not thousands of kilometres away from where the treasure was discovered, but a deposit located only two kilometers from the spot.
