In the early 1st millennium BC the Iberic peninsula was invaded by the Celts and other Indo-European tribes, which occupied the central and western parts of the peninsula and created new cultures on the ruins of the older ones. One of them were Vettones, most probably of Celtic origin. Characteristic for Cogotas II cultures are verraco statues. These are stone bovine statues situated on pasture lands, whose exact usage is still unclear.
