Hawaii is spotlighting Iolani Palace during Hawaiian History Month, a neutral but proud look at the islands' royal past.

• The palace, finished in 1882, was the home of Hawaii's last kings and queens.
• It is the only official royal residence anywhere in the United States.
• It had electric lights and flushing toilets before the White House did.
• The site remains a window into Hawaii before it became a state.

Outlook: Expect more attention on the palace and other island landmarks through the rest of Hawaiian History Month.
