Honouliuli National Historic Site, Oahu

Honouliuli National Historic Site is near Waipahu on the island of Oahu, in the U.S. state of Hawaii. This is the site of the Honouliuli Internment Camp which was Hawaiʻi's largest and longest-operating internment camp, opened in 1943 and closed in 1946. It was designated a National monument on February 24, 2015, by President Barack Obama. The John D. Dingell, Jr. Conservation, Management, and Recreation Act, signed March 12, 2019, redesignated it as Honouliui National Historic Site. The internment camp held 320 internees and also became the largest prisoner of war camp in Hawaiʻi with nearly 4,000 individuals being held. Of the seventeen sites that were associated with the history of internment in Hawaiʻi during World War II, the camp was the only one built specifically for prolonged detention. As of 2015, the new national monument is without formal services and programs. ()
