The Makli Necropolis is located on a plateau six kilometres from the city of Thatta in the Pakistani province of Sindh. The site lies approximately 98 kilometres east of Karachi near the apex of the Indus River Delta.
The Makli Necropolis covers ten square kilometres and houses between 500,000 and one million tombs built over four centuries. This sprawling city of the dead stands as one of the largest funerary complexes in the world.
The Sufi saint Sheikh Hamad Jamali established a khanqah at the site and was eventually buried there beginning a tradition that saw the site rise to prominence during the rule of the Samma dynasty. The 14th century Samma ruler Jam Tamachi venerated the saint and wished to be interred near the saint beginning the tradition of using Makli as a funerary site.
The Samma tombs are strongly influenced by Gujarati styles and incorporate both Muslim and Hindu decorative elements reflecting the cultural synthesis that defined Lower Sindh. The tomb of the King Jam Nizamuddin II completed in 1510 is an impressive square structure measuring 11.4 metres on each side built of sandstone and decorated with floral and geometric medallions.
The most architecturally significant tombs at the site date from around the time of the Mughal era between 1570 and 1640 CE marking a period of intense innovation and artistic expression. The Mughal period is represented by many tombs on the southern side of the necropolis including the mausoleum of Mirza Jani and Mirza Ghazi Baig that of Nawab Shurfa Khan and the enclosure of Mirza Muhammad Baqi Tarkhan.
