In the middle of 16th century, Sher Shah Suri built a fort on the banks of the Ganga understanding the strategic location of the city and importance of the port. The place has continued to be a significant trading centre during Sultanate period and flourished during the rule of Mughals and Nawabs of Bengal.
After a temporary eclipse, in 16th century, Sher Shah Suri returned the city to its former glory and established the present Patna. After the decline of the Mughals , the British too found Patna a convenient regional capital and built a modern extension to this ancient city and called it Bankipore. It was in Gandhi Maidan in this area, that Mahatma Gandhi held his prayer meetings.
