Миль), что делает его вторым самый большой городской район в Португалии. Он признан глобальным городом гамма-уровня Исследовательской группой по глобализации и глобальным городам (GaWC), единственным португальским городом, кроме Лиссабона, который был признан глобальным городом.

Расположенный вдоль устья реки Дору на севере Португалии, Порту является одним из старейших европейских центров, и его историческое ядро ​​было объявлено ЮНЕСКО объектом Всемирного наследия в 1996 году. Западная часть его городской территории простирается до береговой линии Атлантического океана. Его поселение датируется много веков, когда он был форпостом Римской империи. Его объединенное кельтско-латинское имя, Portus Cale, было названо происхождением названия «Португалия», основанного на транслитерации и устной эволюции от латыни.

In 1519, Ferdinand Magellan departed from Seville for the first circumnavigation of the Earth. Coinciding with the Baroque period of European history, the 17th century in Seville represented the most brilliant flowering of the city's culture; then began a gradual economic and demographic decline as silting in the Guadalquivirforced the trade monopoly to relocate to the nearby port of Cádiz.
