Iolani Palace, Honolulu, Hawaii (C) David Cornwell
The only official royal residence in the United States, Iolani Palace played more of a symbolic role for the Hawaiian nation than it did as an actual home. The original palace, demolished in 1874 to make way for the present structure, was the vision of King Kalakaua, a well-traveled magnate who wanted his kingdom to enjoy the status of other modern nations. The palace later served as a place of imprisonment for Hawaiirs last monarch, Queen Liliuokalani.For more information: Iolani Palace

When Henry Francis Du Pontrs collection of American decorative arts outgrew his 100-room European-style country house, he did what any self-respecting tycoon would do: He added 75 more rooms. The manorrs indoor, cobblestone "courtyard" is surrounded by the fronts of four actual colonial-era houses that lend an air of walking down a street from a bygone era.
