Once ruled by a monarchy, Hawaii maintained a palace until the late 1800s. Named Iolani Palace and located on the island of Oahu, it’s the only official royal residence located inside the United States. Interestingly, it’s also considered the only American Florentine style building in existence. The palace’s design elements are indicative of an eclectic combination of Italian Renaissance, Gothic, and Romanesque architecture, yet with a unique Hawaiian island flair.
Some of the window etchings are of native Hawaiian island plants, and instead of flag standards being hung in the monarchy’s palace, kahili, traditional symbols of Hawaii, are displayed throughout. Native Hawaiian woods—mostly koa, but also kamani and kou—are used in the paneling, stairway, doors, and windows.
