The royal apartments occupy four floors of rooms built into the hillside above the river. There are light wells to provide the circulation of air and lighting in the rooms. A flight of steps leads to the apartments, which are linked by a network of passages and corridors. A screen separates the Hall of the Double Axes, which was probably the Guard Room, from the King's Room containing a wooden throne. The Queen's Room is lit by a light well and decorated with a copy of the Dolphin fresco; a tiny bathroom adjoins it.
