Fernando de Noronha (Portuguese pronunciation: [feʁˈnɐ̃du d(ʒ)i noˈɾoɲɐ]) is an archipelago of 21 islands and islets in the Atlantic Ocean, 354 km (220 mi) offshore from the Brazilian coast. The archipelago got its name from the Portuguese merchant Fernão de Noronha, to whom it was given by the Portuguese crown for services rendered regarding wood imported from Brazil. The main island has an area of 18.4 square kilometres (7.1 sq mi) and had a population estimated at 2,718 in 2012. The area is a special municipality (distrito estadual) of the Brazilian state of Pernambuco (despite being closer to the state of Rio Grande do Norte), with about 70% established in 1988 as a national maritime park.
