 Two of the great ceremonial halls still remain within the structure of the Palais de Justice.The palace complex included the residence of the king, with a private chapel, or oratory; a building for the law courts; a large hall for ceremonies; and a "donjon", or tower, which was still standing in the mid-19th century.The palace also had a private walled garden at the end of the island and a private dock, from which the king could travel by boat to his other residences, the Louvre fortress on the Right Bank and the Tour de Nesle on the Left Bank.
