KALIBANGAN

ancient site of the Indus Valley Civilization, in northwestern India (now Rajasthan). This site, discovered by A. Ghosh (director general of the Archaeological Survey of India), is of archaeological significance because it contains both pre-Harappan and Harappan remains; and therein can be seen the transition between the two cultures. Although the pre-Harappan culture worked copper and produced pottery, it had no writing system, and its ruins lack the orderly layout and use of baked brick that is found in the later Harappan sites. The Harappan remains include a cemetery and a fortified citadel.
