The Great Hall contains the throne room of the king. The Iron Throne sits on a raised iron dais with high and narrow steps. A long carpet stretches from the throne to the hall's great oak-and-bronze doors. The cavernous Great Hall can feast a thousand people. The hall is oriented north to south, with high, narrow windows on the eastern and western walls. Skulls of the Targaryen dragons adorn the walls. Located behind the Iron Throne is the king's door, a private exit.

The second-largest chamber in Westeros after Harrenhal, more than a thousand maidens and their family members and servants overcrowded the Great Hall during the Maiden's Day Ball. Small council sessions are sometimes held in the throne room.
