Hawaii was the first state in the nation to legislate that a portion of the taxes paid on commercial building projects be set aside for the purchase of artwork. The state purchased an ornate period-style building (that once was the Armed Services YMCA Building) and in 2002 opened a 12,000-square-foot museum on the second floor dedicated to the art of Hawaii in all its ethnic diversity. HiSAM, as it's nicknamed, has a Diamond Head Gallery featuring new acquisitions and thematic shows from the State Art Collection and the Hawaii Foundation on Culture and the Arts. The Ewa Gallery houses more than 150 works documenting Hawaii's visual-arts history since becoming a state in 1959. A special exhibit on the foundation's 50th anniversary features 130 works by just as many artists and is on view until July 2017. Also included are an outdoor sculpture gallery, a gift shop, a café, and educational meeting rooms. All galleries and programs at the museum are free.
