The famous wall in China is the Great Wall of China, a remarkable feat of engineering and a UNESCO World Heritage site. Construction began during the 7th century BC, with most segments built during the Ming Dynasty (1368-1644). The Wall was initially built to protect against invasions from nomadic tribes and other enemies. Stretching over 13,000 miles, it consists of walls, watchtowers, and fortifications, showcasing the historical military strategies of ancient China. Today, the Great Wall is not only a symbol of China’s historical strength and unity but also a popular tourist destination that attracts millions of visitors each year.
