Easter Island (Rapa Nui) is an island in eastern Polynesia, in the South Pacific Ocean. The island was discovered on Easter Sunday in 1722 by the Dutch voyager Jacob Roggeveen. It is under the administration of Chile. The South American coast is 3,600 km away and the nearest inhabited island is 2,075 km away. The area of the island is 163 km2 and has 7,750 inhabitants. It is made up of three volcanoes that have been joined by lava flows. Around the island there are 15 small islands. There are no permanent watercourses on Easter Island. It has only three freshwater crater lakes. The island is a tourist destination mainly due to the mysterious culture of the ancestors of the Rapa Nui ethnic group. Especially known are the huge stone statues of Moais. UNESCO declared the Rapa Nui National Park in 1995 as a World Heritage Site.
