The castle was completed around the time when King Foltest's previous seat was taken over by a striga, the product of the ruler's incestuous affair with his own sister. Spacious stone halls, stained glass windows and vaulted ceilings indicate that dwarven engineering was employed here. King Foltest is a very active ruler and often travels, though when in Vizima he usually occupies his chambers and generally remains at the castle with his modest court. In the throne room, the King grants audiences to his subjects, be they petitioners or trusted advisors.
The Royal Palace is a region in the third game but limited to one location, the interior of the palace itself and the current Emperor of Nilfgaard, Emhyr var Emreis, who now occupies it. The courtyard has a secret room containing an old letter.
- Foltest's new royal palace briefly appears in the short story comic "The Witcher".
