Mohenjo-Daro Mound of the Dead is an archeological site in the province of Sindh, Pakistan. Built around 2600 BCE, it was one of the largest settlements of the ancient Indus Valley Civilization, and one of the world's earliest major urban settlements, contemporaneous with the civilizations of ancient Egypt, Mesopotamia, and Crete. Mohenjo-Daro was abandoned in the 19th century BCE and was not rediscovered until 1922. Significant excavation has since been conducted at the site of the city, which was designated a UNESCO World Heritage Site in 1980.
Mohenjo-Daro is located in the Larkana District of Sindh, Pakistan, on a Pleistocene ridge in the middle of the floodplain of the Indus River Valley, around 28 kilometers (17 mi) from the town of Larkana. The ridge was prominent at the time of the Indus Valley Civilization, allowing the city to stand above the surrounding plain, but the flooding of the river has since buried most of the ridge in deposited silt. The site occupies a central position between the Indus River and the Ghaggar-Hakra River. The Indus still flows to the east of the site, but the riverbed of the Ghaggar-Hakra on the western side is now dry.
