When Jonah wanted to flee from the Lord, he caught a ship bound for Tarshish. The identity of this place is disputed, but one very common theory is that it refers to Tartessos, located at the mouth of the Guadalquivir in what is now Andalusia, Spain.
Christopher Columbus set sail from Palos de la Frontera, at the mouth of the Guadalquivir, in precisely the same location as ancient Tartessos.
