When you come out of the observatory, walk back down the same corridor until you find the staircase on the right again. Cross the landing, and take the opposite flight of stairs. Right in front of you, you will find a slightly inclined, narrow corridor. Pass through it to enter into the Sultan's Lounge. On the right, you will find a double-compartment kiln, while on the left, you will see the Sultan's maq'ad (i.e., loggia).
