The monument also remembers the tragic fate of 39 people with leprosy who were towed out to sea on July 11, 1943 and never came back.
President Lionel Aingimea was accompanied by war survivor Gaouwa Daoe for the unveiling.
He said the monument is a tribute to the generation of World War II.
“It symbolises the hardship, the struggle, the threatening of our fragile population, the leadership, the determination, the stories of heroes and heroines that have been passed through generations and the remembrance that we as a nation will never forget,” the President said.
