“Bari Aalee Teri Sarkar Hai Nafah-Shah; Mashaa-Allah Sakhi Darbar Hai Nafah-Shah.’
In the present fort area the oldest building inside the fort is a sacred Muhammdan shrine built on an elevated piece of ground near the southern gate. It is said that it was a mazar of a Pir or Saint whose name is still unknown. He is said to have traveled from Persia to Ajmer and from there came down to Munger under the instructions from Khwaza Moin-Uddin Chisti- the famous Sufi Saint and Lived at Munger for many years and also died here in 596 A.H, corresponding to 1177 A.D.
