To the west, it includes the territory of Valdivia through Tierra del Fuego archipelago.Patagonia has two coasts a western one towards the Pacific Ocean and an eastern one towards the Atlantic Ocean.

The name Patagonia comes from the word patagón The original word would probably be in Magellan's native Portuguese (patagão) or the Spanish of his men (patagón).
