The Diwan-i-Khas, or Hall of Private Audiences, was a chamber in the Red Fort of Delhi built-in 1648 as a location for receptions. It was the location where the Mughal Emperor Shah Jahan received courtiers and state guests. It was also known as the Shah Mahal.
A gate on the north side of the preceding Diwan-i-Am audience hall led to the innermost court of the palace called Jalau Khana and the Diwan-i-Khas. Originally there were two enclosures on the west of the hall, one for the nobles and the other for those of a lower rank. These arcaded courts were destroyed after the Indian Rebellion of 1857.
It measures 90 x 67 feet. It consists of a rectangular central chamber, surrounded by a series of arches rising from marble piers. The lower parts of the piers are inlaid with floral designs, while the upper portions are painted and gilded. The four corners of the roof are surmounted by pillared chhatri.
The ceiling, which was originally inlaid with silver and gold, was stripped bare by successive financial crises of the empire by the Jats or Marattas. The current ceiling was installed in 1911.
