The Great Wall of China is often cited as the human-made structure that can be seen from space. However, this claim is somewhat of a myth, as the wall is not easily distinguishable from low Earth orbit without aid due to its materials and the surrounding landscapes. Despite its visibility limitations, the Great Wall stretches over 13,000 miles and serves as a symbol of China's historical efforts to defend against invasions. It showcases remarkable engineering and has significant cultural and historical importance, attracting millions of visitors who come to experience its grandeur.
