Between approximately 1100 and 1200 CE, Polynesian voyagers from Mangareva in the Gambier Islands settled Rapa Nui. The island lies over 3,500 kilometers from the South American coast and 2,000 kilometers from the nearest Polynesian island. The settlers, ancestors of the Rapanui people, developed a culture that included construction of monumental moai stone figures. DNA evidence indicates contact between Rapanui people and indigenous South Americans occurred around 1380 CE. Dutch explorer Jacob Roggeveen became the first known European to reach the island on April 5, 1722.
