- "They blew up my father's castle and all of Alderaan with it."
- ―Leia Organa, to Eneb Ray
The Royal Palace of Alderaan served as the residence of the House of Organa, the royal family of the planet Alderaan. Thanks to the skills of the Alderaanian architects, the palace and the city around it blended smoothly into the local snow-capped mountains. An elegant building, its design captured the opulence of royalty.
One of the palace's balconies overlooked a lake. Leia Organa's childhood bedroom was situated high in one of the palace's towers. Bail Organa's roomy palace office had more than enough space for a desk, a few chairs, and an aquarium full of brightly colored sea creatures.
