Mohenjo-daro (, , IPA: , 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, 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 a UNESCO World Heritage Site in 1980. The site is currently threatened by erosion and improper restoration.
