There are around 1,500 sites of the Indus Valley Civilisation, chief among which are Mohenjo Daro and Harappa. Mohenjo Daro was one of the largest settlements of the ancient Indus Valley Civilization. The historic city was not originally named Mohenjo Daro- Mound of the Dead Men, in fact the city’s name is still unknown. It dates back to 4000 B.C. Mohenjo-daro was the most advanced city of its time, with remarkably sophisticated civil engineering and urban planning. When the Indus civilization went into sudden decline around 1900 BCE, Mohenjo-daro was abandoned. The ruins of the city remained undocumented for around 3,700 years until R. D. Banerji, an officer of the Archaeological Survey of India, visited the site in 1919–20.
Mohenjo-daro is located west of the Indus River in Larkana District, Sindh, Pakistan, in a central position between the Indus River and the Ghaggar-Hakra River. It is sited on a Pleistocene ridge in the middle of the flood plain of the Indus River Valley, around 28 kilometres (17 mi) from the town of Larkana.
