The fort that you see there today was originally the inner citadel of Dinpanah, the city established by Mughal Emperor Humayun in 1533 AD. Sher Shah Suri defeated Humayun in 1540 and rebuilt parts of the fort, calling it Shergarh. Back from exile after 15 long years, Humayun reclaimed the throne, but within a year he fell to his death climbing down some stairs inside the fort. What a chequered past it has seen!
