Mina Masjid or the Heavenly Mosque was built by Shah Jahan between 1631-40 near Diwan-i-Khas in Agra Fort. This small mosque was built, entirely of white marble, by the Mughal king Shah Jahan for his personal use.
It has a small open court in front of the three-arched prayer-chamber. There is no ornamentation and it is simple. It is enclosed and secured on all sides by high walls and, it appears that, Shah Jahan used this mosque during his imprisonment in the adjoining apartment of Musamman Burj, also called shah-burj, from 1658 to 1666 A.D.
