Following his defeat of the Mughal emperor Humayun in 1541, Sher Shah Suri built a strong fortified complex at Rohtas, a strategic site in the north of what is now Pakistan. It was never taken by storm and has survived intact to the present day. The main fortifications consist of the massive walls, which extend for more than 4 km; they are lined with bastions and pierced by monumental gateways. Rohtas Fort, also called Qila Rohtas, is an exceptional example of early Muslim military architecture in Central and South Asia.

Brief synthesis Rohtas Fort, built in the 16th century at a strategic site in the north of Pakistan, Province of Punjab, is an exceptional example of early Muslim military architecture in central and south Asia. The main fortifications of this 70-hectare garrison consist of massive masonry walls more than four kilometres in circumference, lined with 68 bastions and pierced at strategic points by 12 monumental gateways. A blend of architectural and artistic traditions from elsewhere in the Islamic world, the fort had a profound influence on the development of architectural style in the Mughal Empire. Sher Sha Suri, founder of the Suri dynasty, commenced construction of Rohtas Fort (also called Qila Rohtas) in 1541. Irregular in plan, this early example of Muslim military architecture follows the contours of its hilltop site. An interior wall partitions the inner citadel from the remainder of the fort, and an internal water supply in the form of baolis (stepped wells) gave the fort’s garrison self-sufficiency in water. A beautiful mosque known as Shahi Masjid is situated near the Kabuli Gate, and the Haveli (Palatial House) Man Singh was constructed later in the Mughal period. Rohtas Fort represented a new form of fortification, based essentially on Turkish military architecture developed in reaction to the introduction of gunpowder and cannon, but transformed into a distinct style of its own. Rohtas Fort blended architectural and artistic traditions from Turkey and the Indian subcontinent, thereby creating the model for Mughal architecture and its subsequent refinements and adaptations (including the European colonial architecture that made abundant use of that tradition). Most noteworthy are the sophistication and high artistic value of its decorative elements, notably its high- and low-relief carvings, its calligraphic inscriptions in marble and sandstone, its plaster decoration, and its glazed tiles. The garrison complex was in continuous use until 1707, and then…
