In the area of modern Portugal a significant number of towns with Celtic toponymic were already mentioned by ancient Greek and Roman authors. The regions where we can find a greater number of these names are in the north (inhabited by the Callaici or Callaeci) and center (inhabited by the Lusitanians) of Portugal. However, Celtic toponymy occurs throughout the whole country and is also found in the south (the Alentejo, inhabited by the Celtici, and the Algarve, inhabited by the Cynetes), which correspond to the ancient Roman provinces of Gallaecia and Lusitania. The name of Portugal (Portvgalliæ) itself is partly of Celtic origin (see: Name of Portugal and Portus Cale). List of towns and places List of rivers References Falileyev.
