The fort is located in village Dahlil Dero, taluka Sakrand, District Nawabshah; about two kilometers west of the fort is Bharam Khoro village.
Several forts were built in Sindh during the Rae and Brahman dynasties; Dahlil Kot is one of them. Dahlil Kot is constructed in a circular shape, with twelve bastions in it’s circumference. The circular shape symbolises the sun and its twelve bastions signify the twelve signs of Zodiac.
The fortification wall is built of mud, its interior and exterior core was originally covered, as evidence shows, with burnt bricks. It was strengthened by horizontal timber framing; the parapet is crowned by merlons. Loop-holes have been provided in the upper part, for musketry. The circumference of the fortification wall is about 843.68 meters; its diameter is 203.6 meters. The thickness of the fortification wall at the base is about 6 meters, gradually decreasing as it gets higher, giving it a tapered look. At the top, the thickness is about 4.25 meters.
The main entrance to the fort is from a gateway complex on the eastern side; it is an imitation of Mughal architecture (16th and 17th century, A.D.). The entrance is angular in shape, defended by two bastions; one on either side. The entrance has an arched doorway, which now has an iron gate. Above the entrance is an arched panel decorated with rectangular and geometrical designs, with a ventilator in it. Before entering the fort from Shahi Darwaza (Royal Gate), one has to pass through a six meter long passage, which was guarded by soldiers positioned in arched niches, on its both sides. The gateway complex is rectangular. There is a courtyard in the gateway complex with two rooms adjoining the fortification wall of the fort. From the gateway complex to the fort, an entrance, in Mughal style, has been provided, consisting of four chambers, either for guards or as reception rooms. In the entire gateway complex and in the chambers burnt bricks (24 cm x 17 x 4 cm) have been used.
There are twelve semi-circular bastions, equally spaced, around the outer wall; the distance between each bastion is nearly 48.15 meters. The bastions are conical shaped. Their height is about 9.15 meters while the diameter is about 8 meters. The thickness of each bastion is 11 meters. All the bastions are well fortified by machicolations and loopholes for discharge of musketry
The plan of the fort is circular. There are a series of battlements on top of the fortification wall. Another small entrance is provided on the southern side. The double entrance system made the fort more secure against invaders. The fort covers an area of approximately 4 hectares. The fortification was constructed with mud; traces of burnt bricks can be seen in only one bastion of the gateway complex. The fort is in a dilapidated condition. The restoration work of the structure has been started in _______ with an outlay of Rs. 35 million and to be completed within 4 years.
