South of the public area of the Diwan-i-Khas in the Red Fort is the Khas Mahal, where the emperor lived and slept, shielded from prying eyes by lace-like carved marble screens. A cooling channel of water, the nahr-i-bihisht (river of paradise), once flowed through the apartments to the adjacent Rang Mahal, home to the emperor’s chief wife. The exterior of the palace was once lavishly painted; inside is an elegant lotus-shaped fountain.
At the time of research, visitors could not enter the Khas Mahal, but parts of the interior were still visible from outside.
