Easter Island (Rapa Nui: Rapa Nui); (Spanish: Isla de Pascua) is a Polynesian island in the southeastern Pacific Ocean, at the southeastern most point of the Polynesian triangle. A special territory of Chile annexed in 1888, Easter Island is widely famous for its 887 extant monumental statues, called moai (pronounced /ˈmoʊ.аɪ/), created by the early Rapanui people. It is a world heritage site with much of the island protected within the Rapa Nui National Park. Historically the island has experienced a collapse of its ecosystem, with extinction of many of its prehistoric species; these events were associated with over-exploitation of the island’s resources. The underlying island geology is one of extinct volcanoes.
