The Celts in the Iberian peninsula were traditionally thought of as living on the edge of the Celtic world of the La Tène culture that defined classical Iron Age Celts. Earlier migrations were Hallstatt in culture and later came La Tène influenced peoples. Celtic or (Indo-European) Pre-Celtic cultures and populations existed in great numbers and Iberia experienced one of the highest levels of Celtic settlement in all of Europe. They dwelt in northern, central and western regions of the Iberian Peninsula, but also in several southern regions.
