Royal Palace of Oz
From Oz Wiki
The Royal Palace of Oz stands in the center of the Emerald City and is the home of Princess Ozma.
Description
The building is vast and noble and elegant. The grand staircase is carpeted thick with velvet.
The Throne Room is an immense domed chamber in the center of the palace. The Royal Throne is made of solid gold and encrusted with enough precious stones to stock a dozen American jewelry stores. There is a balcony large enough for an orchestra, and two electric fountains which spray colored perfumed water nearly as high as the arched ceiling.
The gardens and ample grounds are surrounded by a green marble wall set with emeralds.
Every resident and regular guest has a private apartment, usually consisting of several rooms. Dorothy has a suite as do her uncle and aunt.
Background
In her books, Ruth Plumly Thompson often calls Ozma's palace a "castle" — which is not the same thing.
Kenneth Gage Baum gives the royal palace a lightning-powered clock called the Metachron that controls time in Oz. (The Dinamonster of Oz)
