Large towns with stone walls appeared in two different areas of the Iberian Peninsula: one in the Portuguese region of Estremadura (culture of Vila Nova de Sao Pedro), strongly embedded in the Atlantic Megalithic culture; the other near Almería (southeastern Spain), centred around the large town of Los Millares, of Mediterranean character, probably affected by eastern cultural influxes ("tholoi"). Despite the many differences, bith civilisations seem have had friendly contact and to productive exchanges. In the area of Dordogne (Aquitaine, France), a new unexpected culture of bowmen appears: the Artenac culture soon takes control of western and even northern France and Belgium. In Poland and nearby regions, the putative Indo-Europeans reorganised and reconsolidated with the culture of the Globular Amphoras. Nevertheless, the influence of many centuries in direct contact with the still-powerful Danubian peoples had greatly modified their culture.
