The Lahore Fort is a citadel located in the city of Lahore, Pakistan that was originally constructed during the reign of Mughal emperor Akbar in the 16th century. It has since been upgraded and expanded by subsequent Mughal rulers. Some notable sites within the fort include the Sheesh Mahal palace with its mirror work, Moti Masjid mosque, and Alamgiri Gate, the main entrance built in 1673. The fort was inscribed as a UNESCO World Heritage Site in 1981 and demonstrates the rich architectural traditions of the Mughal Empire.
