English: Hajiganj Fort also known as Khizirpur fort, situated at Hajiganj locality of Narayanganj, Bangladesh, on the western bank of Shitalakshya. The exact date of Hajiganj fort is uncertain but it may have been built soon after Subahdar Islam Khan established the Mughal capital at Dhaka. The fort, quadrangular in size, consists of a pentagonal curtain wall machicolated for muskets with rounded corner bastions. On the inner side of the curtain wall there is a 1.22 m high rampart walkway from the base of the curtain wall which is itself pierced by several musketry holes. The holes are wider meant probably for 'gun firing at the pirates proceeding up the river'. In a corner of the fort enclosure there is a tall free standing square column of brick which must have been used for observation and placing guns in the rainy season.
