Large, detailed map of Portugal and adjacent provinces of Spain, with an inset map of coastal Brazil. The title of the map refers to the position of the Algarve as a semi-autonomous region within Portugal.

The map of Portugal is colored by province and the map of Brazil by captaincy. The map of Brazil contains a small title cartouche, with a scene of natives apparently engaged in cannibalism. The main title cartouche is decorated with figures symbolizing Portugal’s maritime prowess. A lengthy note below the cartouche describes the territorial expanse of the empire.

Two sea battles from the recent War of the Spanish Succession are pictured in the Atlantic; the upper scene shows the sinking of Spanish treasure ships by an Anglo-Dutch fleet in the Battle of Vigo Bay, and the lower image shows an unnamed battle between the Spanish Fleet and an English fleet bringing Charles III to Lisbon.
