Archaeologists have discovered a palatial construction with an audience hall which makes up the first specifically political precincts built in continental Europe. A prince’s tomb in the subsoil contains the largest amount of grave goods from the Bronze Age existing in the Iberian Peninsula. Some of the most outstanding items include a silver diadem of great scientific and patrimonial value, the only one conserved from that era in Spain, as well as four golden and silver ear dilators.
