Mohenjo-daro (lit. Mound of the Dead Men)is an archeological site in the province of Sindh, Pakistan. Built around 2500 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, Minoan Crete, and Norte Chico. Mohenjo-daro was abandoned in the 19th century BCE as the Indus Valley Civilization declined, and the site was not rediscovered until the 1920s. Significant excavation has since been conducted at the site of the city, which was designated an UNESCO World Heritage Site in 1980.The site is currently threatened by erosion and improper restoration.
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. The ridge was prominent during the time of the Indus Valley Civilization, allowing the city to stand above the surrounding flood, but subsequent flooding has since buried most of the ridge in silt deposits. The Indus still flows east of the site, but the Ghaggar-Hakra riverbed on the western side is now dry.
