or Hall of Private Audience was used by the emperor for the reception of
important guests such as kings, ambassadors and nobles in private and to
deal with important affairs of the state. Constructed in 1635, it had
two halls and the interior hall was known as Tambi khana. Diwan-i-Khas
had a flat wooden flat ceiling covered with gold and silver leaves in
relief to imitate the rays of the sun. Open on three sides, one can
enter it through five arched openings supported on double columns.
Unlike other architectural example of Shah Jehan's time, it had no
chhatris over the parapet. The Persian inscription inside the interior
hall inlaid in black stone and dated 1636-37 compares the room to the
highest heaven and the emperor to the sun. The chambers were profusely
decorated with highly refined inlay work in floral patterns on the
borders of the dados and exquisite carvings in the middle in relief. The
work was done judiciously on the places selected carefully to present
the work in the best possible manner.
