The Rohtas fort is one the largest and most formidable fort located near the modern city of Jhelum in the northeast of Pakistan. The fort was built under the rule of Sher shah Suri, the founder of the Suri dynasty in order to stop the return of Mughal Emperor Humayun but also to suppress the local Gakhar tribes of Potohar.

The name of the fort is derived from the stronghold at Rohtasgarh in Shahabad district which Sher Shah Suri captured from a Hindu prince in 1539. The construction of the fort started in 1541 under the supervision of his revenue minister, Todar Mal Khatri.

The strong complex fortified is a blend of architectural and artistic traditions from the Islamic countries in Central and South Asia. The layout of the fort is triangular and is made up of huge walls that extend for more than 4 kilometers, 68 bastions and 12 major gates all of which are being built in ashlar stone.

The fort contains calligraphic inscriptions in marbles and sandstone, high and low relief carvings, plaster decorations, and glazed tiles. There is a small courtyard and a prayer chamber inside the fort. It  contains numerous remaining architectural relics, including the Shahi Mosque and the Haveli Man Singh. Sher Shah Suri died before the completion of the fort and it came under the control of Mughals Empire. Later on, the fort became the capital of Gakkars.

According to historic references, it has been one of the longest military bases from 16 century till 19 century. However, the fort has been severely damaged due to various attacks. It is still one of the great tourist attractions in Punjab, Pakistan, and a large number of tourists paid a visit to this fort. Rohtas Fort was inscribed as a UNESCO world heritage site in 1997.
