4. The Great Wall of China
The Great Wall of China has endured relentless assaults from nature and humans alike. Erosion, vandalism, and nearby farming have damaged or destroyed many sections. In recent decades, Chinese authorities and local communities have launched extensive restoration campaigns to safeguard this magnificent feat of engineering. Their work has helped rescue long-neglected stretches and ensure the Wall’s legacy continues. Dive deeper into these preservation efforts at Smithsonian Magazine.
