Makli Necropolis is one of the largest funerary sites in the world, holding between 500,000 and 1 million tombs across 10 kilometres near Thatta in Pakistan's Sindh province. It was built up over a period of 400 years and was inscribed as a UNESCO World Heritage Site in 1981.
Makli Necropolis sits on a plateau about 6 kilometres from Thatta, roughly 98 kilometres east of Karachi near the apex of the Indus River Delta in southeastern Sindh. Its southernmost point lies about 5 miles north of the ruins of the medieval Kallankot Fort.
According to legend, a Hajj pilgrim fell into spiritual ecstasy at the site and declared it Makkah for him, leading the Sufi saint Sheikh Hamad Jamali to name it Makli, meaning Little Makkah. Historian Ali Ahmad Brohi instead traces the name to an ancient Mahakali, or Maa Kali, temple, since historical evidence does not confirm the legend.
Makli Necropolis holds tombs of royalty, Sufi saints, and esteemed scholars, including the Samma king Jam Nizamuddin II, his adoptive son Darya Khan, and Tarkhan rulers such as Isa Khan Tarkhan I, Isa Khan Hussain II Tarkhan, and Jan Beg Tarkhan.
The tradition began after the Sufi saint Shaikh Jamali was buried there, when the 14th century Samma ruler Jam Tamachi asked to be interred nearby. The most architecturally significant tombs at the site date from around the Mughal era, between 1570 and 1640 CE.
Makli Necropolis is known for the Chaukhandi style, which blends Muslim, Hindu, Persian, Mughal, and Gujarati influences into carved sandstone tombs, domed canopies, and blue tile-work. The style is named after the Chaukhandi tombs near Karachi.
