Which of the following sites of the Indus Valley Civilization is unique for having a lower town that was also fortified?

💡 Solution & Explanation

Kalibangan is exceptionally unique among Indus Valley Civilization settlements because both its citadel area and the residential lower town were individually surrounded by massive fortification walls. Most other Harappan urban centers typically fortified only the western citadel while leaving the lower settlement unfortified. This archaeological feature highlights distinctive defensive and urban planning strategies practiced in the region.
