Shah Jahan commissioned the Diwan-i-Khas in the mid-17th century as part of his ambitious renovations to the Agra Fort. Constructed primarily of white marble, the hall replaced an earlier structure built by Akbar. It served as a venue for private discussions, diplomatic meetings, and important state affairs. The famous Peacock Throne, studded with countless jewels, was once housed here before being looted by Nadir Shah in 1739. The Diwan-i-Khas stands as a testament to the opulence and artistry of the Mughal dynasty during its peak.
