The early history of the fort is shrouded in mystery and nothing definite is known about it as traditionally it is stated that the fort was built as early as the city itself and its foundation is attributed to mythic Loh a son of the hero of Ramayana of legendry age (1200-800 BCE). The natural soil of the fort formed four distinct periods, British and Sikh, Mughal, Pre-Mughal and Pre-Muslims. Below the levels of the pre-Mughal period, the remains of non-Muslims or Hindu period were brought to light. Lahore fort is the only place in Pakistan, which represents the different phases in the development of Mughal architecture. Fort is irregular in plan, being about 460 east to west by some 360 m north to south, girdled round by a fortification wall constructed in small burnt bricks. The important buildings of the fort are Dault Khana-e-Khas-o-Am, sleeping chamber of emperor Jahangir, Shish Mahal, Diwan-e-Am, Diwan-e-Khas, Moti Masjid, Alamgiri Gate etc.
