The Waialua Sugar Mill is the center of this town and the historical base of its plantation history.
In 1895, Álvarez resigned his position in Waialua to prepare himself for work as Superintendent of a new experimental hospital for the treatment of leprosy which was to be established in Kalihi, a suburb of Honolulu.
The campus boasts the painted plastic mural A Waialua Day by Balazs Szabo and the mixed media sculpture Waialua from Ken Shutt’s Konohiki Series.
