Hao, or Haorangi, is a large coral atoll in the central part of the Tuamotu Archipelago. It has c. 1000 people living on 35 km2 (14 sq mi). It was used to house the military support base for the nuclear tests on Mururoa. Because of its shape, French explorer Louis Antoine de Bougainville named it "Île de la Harpe" (Harp Island).
