Namak Haram Deorhi refers to both the place of Mir Jafar and the main gate which leads to the palace.

The House of Jagat Seth, Jafarganj Cemetery, Nashipur Rajbari, Kathgola Palace and Tomb of Azimunissa Begum are all located nearby.

According to Seir Mutaqherin, Nawab Siraj ud-Daulah was murdered by Muhammad-Ali-Beg on the orders of Mir Miran in the campus of this Deorhi,[1] beside the public road under a Neem tree on 2 July 1757 after he fled to save his life, after he was defeated in the Battle of Plassey.

But, according to historian Robert Orme, he was seen to be murdered inside the Mansurganj Palace, on the west banks of the Bhagirathi River, opposite to this Deorhi.

The next morning, his body was placed on an elephant and paraded through the streets of Murshidabad and also past Siraj ud-Daulah's mother, Amina Begum's house.
