This grand street was laid out by Jahanara Begum, daughter of Shah Jahan. From the Lahore Gate of the fort to the end of the Chandni Chauk the street was about 40 yards wide and 1,520 yards long. Through the center of this street ran the canal of 'Ali Mardan, shaded on both sides by trees. On the eastern end of the Chandni Chauk stands the Lahore Gate of the Fort, and on the opposite end the handsome mosque of Fatehpuri Begam.
