What is a boundary relic, and which historical example illustrates it?

• A. A relic boundary is a current border across water.
• B. A relic boundary is a boundary drawn by climate zones.
• C. A relic boundary is a former border area that continues to influence identity or landscape, though no longer a boundary; example: The Great Wall of China as a historical boundary.
• D. A relic boundary is a boundary that never existed.

Answer: (C)

A boundary relic is a former political boundary whose line no longer functions as a border but still shapes the landscape and people’s sense of place. The Great Wall of China fits this well: it marks a historical frontier, and its presence—and the sites and landscapes it created—continue to influence how regions are viewed and experienced, even though it is not an active border today. This contrasts with a current border across water, a boundary defined by climate zones, or a boundary that never existed, which do not embody the idea of a relic boundary.
