To its north and west is the Atlantic Ocean. It is the third largest peninsula of Europe with an area of 582,860 km². The name Iberia is the Ancient Greek name for the area which the Romans called "Hispania". The word Hispania is now used for Spain, while the word Iberia is used for the whole area.
