ミーニョ川
In 868, Vímara Peres, a Christian warlord from Gallaecia and a vassal of the King of Asturias, Léon and Galicia, Alfonso III, was sent to reconquer and secure from the Moors the area from the Minho River to the Douro River, including the city of Portus Cale, and founded the First County of Portugal or Condado de Portucale. "Portus Cale" is thus the former name of current-day Porto and Vila Nova de Gaia's riverside area, that would be used to name the whole region and, later, the country.
