Mohenjo-daro (Sindhi: موئن جو دڙو, IPA: [muˑənⁱ dʑoˑ d̪əɽoˑ], lit. Mound of the Dead; English pronunciation: /moʊˌhɛn.dʒoʊ ˈdɑː.roʊ/) 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. The site is currently threatened by erosion and improper restoration.
