Built around 2600 B.C., Mohenjo-daro was one of the largest settlements of the ancient Indus Valley Civilization. The city would have been contemporary with the civilizations of ancient Egypt, Mesopotamia and Crete. The site provides early evidence of systems of town planning, and the city likely exercised a considerable influence on the subsequent urbanization of the Indian peninsula.
