This fort was constructed in 1660 AD on the western bank of the Ichamati River by Mir Jumla, the Mughal Subadar and Commander-in-Chief of Bengal. Encircled by waterways, the partially submerged remnants of this brick fort provide protection from the frequent looting carried out by Portuguese and Mughal pirates.
This is an 82-by-72-meter oblong fort. There are rumors that an underground tunnel connected this fort to the fort of Lalbagh in Dhaka. Every corner of this fort’s defense wall features a circular bastion. Sand fills it to a considerable extent up to the bastion, where a battlemented parapet with musketry apertures runs.
The northern gateway is the only one with arches. This river fort’s massive (32.81 dig meter) circular platform on the river side is one of its most outstanding features. Evidently, this enormous plate was utilized as both a watch flower and a cannon mount. The original wall is joined by another wall that encircles the platform. It is regarded as a special Mughal monument. In Munshiganj, Idrakpur Fort is located by the Dhaleswary River.
