>>1370325>CelticThe Iberian Peninsula was an area heavily influenced by Celtic culture, particularly the ancient region of Gallaecia (about the modern region of Galicia and Braga, Viana do Castelo, Douro, Porto, and Bragança in Portugal) and the Asturian region (Asturias, León, Zamora in Spain). Only France and Britain have more ancient Celtic place names than Spain and Portugal combined (Cunliffe and Koch 2010 and 2012).
