Portus Cale was an ancient town and port in present-day northern Portugal, in the area of today's Porto and Vila Nova de Gaia.
Cale was an early settlement located at the mouth of the Douro River, which flows into the Atlantic Ocean in the north of what is now Portugal.
At the end of Brutus's campaigns, Rome controlled the territory between the Douro and Minho rivers plus probable extensions along the coast and in the interior.
It was only under Augustus, however, at the end of the 1st century BC, that present north Portugal and Galicia were fully pacified and under Roman control.
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.
