Rohtas Fort is situated in approximately 16 km north west of Jhelum district of Punjab Pakistan and 7 km from Dina. It was constructed on a hillock where the tiny Kahan river meets another rainy stream called Parnal Khas and turns east towards Tilla Jogian Range. The fort is about 300 feet above its surroundings. It is 2660 feet (818 meters) above sea level and covers an area of 12.63 acres.
Rohtas Fort is a garrison fort built by the great Afghan king Sher Shah Suri. This fort is about 4 km in circumference and the first example of the successful amalgamation of Pukhtun and Hindu architecture in the Indian Subcontinent.
Sher Shah Suri named Qila Rohtas after the famous Rohtasgarh Fort in Shahabad district near Baharkunda, Bihar which he captured from the Raja of Rohtas Hari Krishan Rai in 1539. Rohtasgarh is situated on the upper course of the river Son, 20 37’ N and 85 33’E. It was built by Harish Chandra of the Solar dynasty and was named after his son Rohitasva after whom the fort (Rohtasgarh) was named.
Sher Shah constructed Qila Rohtas to block Emperor Humayun’s return to India after defeating him in the Battle of Kanauj. This fort lies on the old GT road between the North (Afghanistan) to the Plains of Punjab. It blocked the way from Peshawar to Lahore. The other reason was to suppress the local tribe of this region Potohar called Gakhars who were allies of Humayun and refused their allegiance to Sher Shah Suri. The Emperor instructed the local Janjua Rajput tribe to help construct the fort to crush the Gakhars when the latter became openly defiant and persecuting labourers who attended the construction.
The Fort was built by Todar Mal under orders of Sher Shah.
Sher Shah threatened to construct such a fort in that country that it should not only effectually restrain the Ghakkars, but also the passage of the Mughals. He therefore himself made a tour through the hills of Girjhák Ninduna [mountains circumjacent], *and finding a fit spot, he laid the foundations of the fort, which he called Rohtás.
Besides that, he sent a large force against Ráí Sárang, the Ghakkar, and not only was the country subdued, and the hill of Balnáth plundered, which was then the residence of the Dárogha of that tract, but the daughter of its chief was taken prisoner, and conducted before Sher Sháh, who presented her to Khawás Khán; upon which Ráí Sárang, they relate, sent a quantity of [hemp] blankets and millet to Sher Sháh, with the remark that in such only consisted their raiment and food, besides which they could afford nothing; according to others, he sent a lion’s skin and some [arrows] spears, which he said was their only property. With this conduct, however, Sher Sháh was by no means satisfied. Sárang [Sárang’s troops] being weakened by [skirmishes] the attacks of the holy warriors, and greatly reduced and straitened, submitted himself in person to Sher Sháh, who ordered him to be flayed alive, and his skin to be filled with straw, and so pay the penalty of his misdeeds.
Sher Sháh issued farmáns to complete the fortifications of Rohtás; but Todar Khatri represented that the Ghakkars, to whom that country belonged, would not allow any one to work for wages; and that they had agreed amongst themselves, upon oath, to expatriate every person that should contravene their wishes. Sher Sháh, in answer, told him [that he should not be allowed to give up that work, which he only wished to do in consequence of his greediness for gold that the work did not seem to advance under his superintendence, and that a man who was fond of money, and was alarmed about disbursing it, would never accomplish the king’s designs.
Todar, on the reception of this fresh command, fixed first a golden ashrafí as the enormous remuneration for one stone, which induced the [Kakers] Ghakkars to flock to him in such numbers that afterwards a stone was paid with a rupee, and this pay gradually fell to five tankas, till the fortress was completed.
