Lahore.

Lahore Fort and Shalimar Gardens are located in Lahore, a cultural city in eastern Pakistan. Known as the "Soul of Pakistan" for its brilliant Mughal culture and dazzling Mughal architectural art, this is a treasure of Mughal architecture and a must-visit place. The predecessor of this ancient castle was a mud fort, which was built in 1021 AD. At that time, it was just a military fortress built of mud. In 1566 AD, Emperor Akbar of the Mughal Empire built a brick and stone fortress surrounded by high walls to resist foreign invasions after demolishing the old city. As Lahore gradually became a commercial center and summer capital on the South Asian subcontinent, successive emperors of the Mughal Empire continued to add and expand gardens, fountains, and palaces in the ancient castle, making the original military castle a magnificent royal garden. The patterns on the ancient castle are all dyed with plant dyes, so they are now severely weathered. They are also being slowly repaired, but it is difficult to restore them to their previous beauty.
