* The Ilhas Selvagens (Savage Islands). The archipelago is under Portuguese domination but is geographically closer to the Canary Islands (165 km) than to Madeira (280 km). Found in 1364 by Italian navigators, the islands belonged to private owners until 1971, when the Portuguese government bought them and established a natural reserve area covering the whole archipelago. The islands have been claimed by Spain since 1911 and the dispute has caused some periods of political tension between the two countries. The main problem is not so much their intrinsic value but the fact that they expand the Exclusive Economic Zone of Portugal considerably to the south.
