Give a descriptio

The site of Kalibanga features two mounds of city planning. The Eastern mound has evidence of common settlement while the Western mound has fort with safety walls around it.
It also features the oldest evidence of ploughed fields. It also features other common structures like public drainage, brick and clay walls and garbage collection earthen pots.
Other unique evidence like ruins of fire altars and agricultural tools made of copper are also found. Earthen pots and bricks were most probably baked in sunlight. The seals found in this region feature the Sendhav script that is still undeciphered. Three graves have also been found which indicate the religious beliefs towards death and afterlife.
