A masjid (mosque) called the Moti Masjid (pearl mosque), built by Bahadur Shah I (d.1712), was a private mosque of the royal family, which has now been subsumed within the palace precincts. The mosque is a small and unique three-domed structure made of white marble. Its construction is also credited to Bahadur Shah. The austere mosque has the mihrab on the west direction of prayer but is unusually not embellished, except for little border of floral carving on the south at the top edge of a dado.
