A Harrapan town, one of the most important of the southern Indus Civilization sites, at the head of the Gulf of Cambay, northwestern India. Besides typical Indus structures like a walled citadel, granary, drainage system, and a grid street plan, it had a dock faced with baked brick. There were residential and craftworking (shell, bone, bead, copper, gold) areas. The site was important for its sea trade, as shown by the discovery of a Dilmun seal from the Persian Gulf. There were also contacts with the Chalcolithic cultures of the Deccan peninsula and the practice of rice cultivation which had been introduced from further east. There was much local non-Harappan pottery in the Mature Harappan levels. Radiocarbon dates place it in the later 3rd millennium BC (c 2400-2100 BC).
