Thatta

 city, UNESCO World Heritage Site

Thatta or Thatto (Sindhi:ٺٽو), is a historic town of 22,000 inhabitants in the Sindh province of Pakistan. Its major monuments are listed among the World Heritage Sites.
The city, formerly commanding the delta of the Indus, was the capital of Lower Sindh from the 14th century. Since 1592, it was governed in the name of the Mughal emperors of Delhi. After the province was ceded to Nadir Shah of Persia in 1739, Thatta has fallen into neglect.
Thatta's monuments include the Jama Mosque, built by Shah Jahan in 1647-49 and lined with glazed tiles. There are also the tombs of Jam Nizamuddin (reigned in 1461-1509), several Tarkhan rulers and Mughal officials. A vast old necropolis with thousands of graves may be found at the nearby Makli Hills.
