Lower Paleolithic
The Lower Paleolithic period, the work of Homo erectus, left very few remains in the Basque Country. The first settlers may have arrived in the Riss-Würm interglacial period, between 150,000 and 75,000 BP, carrying with them the Acheulean technology. These people settle mainly in the lowlands, near the rivers Ebro and Adour, in the regions of Araba, Navarre, Labourd and Lower Navarre.
