Eiao

Eiao is the largest of the extreme northwestern Marquesas Islands. The island was discovered in 1791 by the American sea captain Joseph Ingraham, who named it Knox Island in honour of the U.S. Secretary of War at that time, Henry Knox. Other names given to this island by Western explorers include Masse, Fremantle, and Robert.

Eiao is administratively part of the commune of Nuku-Hiva, itself in the administrative subdivision of the Marquesas Islands.

The center of this island is a high plateau, rising on the east side to 576 metres above sea level, much of which has been devastated by herds of feral sheep brought here by mankind.
