Spain, officially the Kingdom of Spain, is a sovereign state and a member state of the European Union. It is located on the Iberian Peninsula in southwestern Europe. Its mainland is bordered to the south and east by the Mediterranean Sea except for a small land boundary with Gibraltar; to the north and north east by France, Andorra, and the Bay of Biscay; and to the west and northwest by Portugal and the Atlantic Ocean. It is one of three countries—France and Morocco are the other two—to have both Atlantic and Mediterranean coastlines. Spain's 1,214 km border with Portugal is the longest uninterrupted border within the European Union.
Spanish territory also includes the Balearic Islands in the Mediterranean, the Canary Islands in the Atlantic Ocean off the African coast, three exclaves in North Africa, Ceuta, Melilla, and Peñón de Vélez de la Gomera that border Morocco, and the islands and peñones of Alborán, Chafarinas, Alhucemas, and Perejil. With an area of 505,992 km², Spain is the second largest country in Western Europe and the European Union, and the fifth largest country in Europe.
