Jafarganj Cemetery was built by Mir Jafar over an area of 3.51 acres within an enclosure of waved walls, about half a mile north to the Nizamat Fort Campus and inside the campus of Namak Haram Deorhi. It hosts the graves of the later Nawabs of Bengals of the Najafi dynasty, starting from Mir Jafar, and their family members while Khushbagh, which was built by Nawab Alivardi Khan, hosts the graves of the Nawabs of Bengal belonging to the Afshar dynasty and their family members. At present this graveyard is controlled and maintained by the Archaeological Survey of India.
It is said that earlier there was a "Kitchen Garden" at the site of this cemetery which Shah Khanaum Begum (Mir Jafar's wife and Alivardi Khan's sister) was very fond of.
