Zeenat-ul Masjid also commonly known as Ghata Masjid (cloud mosque) was built in the year 1707 AD by Zinat-ul-Nissa, Aurangzeb's second daughter, and is located in Daryaganj, Delhi. 

A few years after the siege of Delhi in 1857, the Hindustan British Government gave the charge of this mosque to Anjuman Muayyed-ul-Islam for its maintenance and protection, later it was taken over by the Sunni Majlis-E-Awakf. 

The mosque is like a miniature version of Jama Masjid and remains in acceptable condition even today.
