Khirigsuurs are stone monuments of variable scale and complexity that dominate the archaeological landscape of the Mongolian Bronze Age. Though there are countless typical-sized monuments, there are a few very large structures suggesting that a chiefly hierarchy directed their construction. Using measurements of size and formal complexity to compare these mega-monuments and khirigsuurs within fully surveyed areas this article argues that these monuments are not primarily tombs built to represent the social hierarchy of early nomadic pastoralists. Instead, they are monumental places created for living communities to communicate their organization and enduring nature to others and themselves. This communication was essential for early pastoralist communities to become established and survive.
