Some of the first and most characteristic examples that remain of early Mughal architecture were built in the short reign (1540–1545) of emperor Sher Shah Suri, who was not a Mughal; they include a mosque known as the Qila-i-Kuhna mosque (1541) at Purana Quila, Delhi, and the military architecture of the Old Fort in Delhi, the Lalbagh Fort in Bangladesh, and Rohtas Fort, near Jhelum in Pakistan.
Archaeological Survey of India (ASI) carried out excavations at Purana Qila in 1954–55 and again from 1969 to 1973 by B. B. Lal, and its findings and artefacts are exhibited at the Archaeological Museum, Purana Qila.
