Rohtas Fort (Urdu: قلعہ روہتاس Qila Rohtas) 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 sub-continent. 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 tribes of this region Potohar called Gakhars who were allies of Humayun and refused their allegiance to Sher Shah Suri. The Gakhars made a feeble retort by building some fortifications near the village of Sultanpur, which still remain today. (More...)
