This Mughal architecture style mosque was built by a Islamic preacher named Shah Neyamat Ullah.^[2]

The mosque has three access points. It is 33 feet tall, 33 feet wide and the walls of the mosque are about 6 feet wide.^[3] Shah Neyamat Ullah came to this region with some disciples in 1659 when Shah Shuja was the governor of Bengal and Odisha.
