Balakot was one of the Harappan centres that specialized in making shell objects.
Archaeological evidence from Harappan sites indicates specialization in various crafts. Balakot, located near the coast (present-day Pakistan), was an important centre for the production of shell objects, likely due to the availability of raw material. Kalibangan is known for ploughed fields and fire altars. Mohenjo-daro was a major urban centre with monumental architecture. Banawali yielded evidence of a toy plough and good quality barley.
Other Harappan centres known for specific crafts include Chanhudaro (bead making), Lothal (bead making, shell work, metallurgy), and Dholavira (water management, large inscriptions). This specialization points towards a sophisticated economic and trade network within the Indus Valley Civilization.
