Introduction to the ancient city of Thatta: The ancient city of Thatta is located in the Indus Delta, southeast of Karachi. It was a prosperous port city 300 years ago. There are two ancient mosques and ancient royal tombs, built by King Shah Jahan during the Mughal Dynasty, with typical Persian style. In addition to some dilapidated dwellings, only tombs, spiritual temples and mosques remain in the ancient city of Thatta, vaguely showing its former glory, and it is known as the "lost city".
