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.
