To the west of the Hammam lies the small mosque, called the Moti Masjid (‘pearl mosque’), built by Aurangzeb for his personal use. The prayer-hall of the mosque is inlaid with outlines of musallas (small carpets for prayers) in black marble, and it stands at a higher level than the courtyard.

The hall is surmounted by three bulbous domes, originally copper-plated, which appear to be too constricted at the neck. The eastern door is provided with copper-plated leaves. The mosque was also used by the ladies of the seraglio.
