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 Pashtun 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.
