The first floor of the north gate tower has already been described. The east door of room 90 communicates with the vaulted and unlighted room, 93. A thin dividing wall separates room 93 from room 94 (there is a small aperture like a window in this wall). Beyond another thin dividing wall lies room 95, with a window at its eastern end looking into the palace yard. These three rooms, 93, 94, and 95, occupy the space above the east corridor, 6. Room 107 is on a lower level; it is approached from 93 by a doorway with steps and is wholly unlighted. The group of rooms Nos. 103, 104, and 105 are on the same level as 107. They are 14·75 metres long and correspond in width with the rooms below them. At their western end they are provided with a masonry divan, 1·20 metres wide and raised ·55 metre above the level of the floor. The meaning of this divan is apparent in the section (section _a-b_, Plate 4, Fig. 1); it was needed in order to lift the floor of the three rooms above the vaulted tube which lies parallel to the vault of the great hall. The height of these rooms from the floor to the top of the vault is 4·20 metres. They communicate with each other and with the vaulted passage 108, and room 103 possesses further a door in the south wall leading into room 102. The latter returns to the level of rooms 93, 94, and 95, and consequently steps are placed in the doorway of 103. At the north end of the passage 108 there is a door sunk below the level of the floor and covered by an arch oversailing the jambs (Plate 21, Fig. 2). It communicates with the ramp which comes up from the great hall. East of this door there are the remains of an engaged column, and it is obvious that the passage must have been flanked here by an open arcade (Plate 3, Fig. 1). Steps in the doorway at its southern end lead up to room 106, which is on the same level as 102. South of court A lie three rooms, 109, 110, and 111. They are not as deep as the rooms below them on the ground floor (4·40 metres as against 5 metres) since space has to be provided for a narrow ledge above court A. On to this ledge the north doors of the three rooms open. On the north side of court A the ramp, after passing the doorway of 108, is continued upwards (its windows can be seen in the wall of the court (Plate 22, Fig. 1)). A wide doorway opens on to a stair, which will be described later, coming up from the palace yard. The ramp is then carried on along the east side of court A, and finally opens on to the roof of 111 and of the narrow passage to the east side of it. The last portion of the ramp is ruined, but traces of the vault which supported its floor can be seen in the east wall of court A, together with the spring of the vault with which it was roofed. Between the ramp and the vault of 25 there appears to have been a vaulted passage, very low at its northern end, and lighted by a rectangular window which overlooks the palace yard. It opened at
