In the Mughal days, the Old City was surrounded by a 9 meter high brick wall and had a rampart running around it which served as a protection for the city. A circular road around the rampart gave access to the city through thirteen gates. Some of the imposing structures of these gates are still preserved.
Here are the photos of the Lahore Antique Gates & Historical Gates of Mughal Times. They all are almost lost their originality due to no preservation work done by Govt. but we get some photos to save the History.
