A few of the Calcolithic sites excavated so far have revealed traces of mud-brick or mud ramparts and bunds. However, these have not been explored or exposed to an extent where their plans, strategic situation etc. could be made out. Hence for the period of circa 1700 BC to 500 BC, one has to remain satisfied by mentioning the possibility that some of early farming communities perhaps had rudiments of fortifications around them.
