Wall of China (in the context of the history of China)

The Great Wall of China is a series of fortifications built to protect Chinese states from invasions. Construction began in the 7th century BC, with significant expansions during the Ming Dynasty (1368-1644). Spanning over 13,000 miles, it showcases ancient engineering and military strategy. The Wall also symbolizes China's historical strength and cultural identity. While primarily a defensive structure, it facilitated trade, especially along the Silk Road. Today, it stands as a UNESCO World Heritage site and a popular tourist destination, reflecting both the power and the complexities of Chinese history.
