The District of Setubal is located in the South of Portugal, the District Capital is the city of Setubal. It is delimited by the districts of Lisbon and Santarem on the north, the district of Evora on the east, the district of Beja on the south and the Atlantic Ocean on the west. The River Sado empties at the city of Setubal, which has been a fish-salting centre since the 1st century. After the Moorish invasions in the 4th century, it declined and the sands moved in. The town really developed during the Age of Discoveries when King Afonso V sailed from the port of Setubal in 1458 for Morocco, where he conquered Alcacer Ceguer.
