The Great Wall of China (historical reference)

The Great Wall of China is a series of fortifications built primarily to protect Chinese states and empires from invasions. Construction began over 2,000 years ago, with significant contributions during the Ming Dynasty (1368–1644). The Wall stretches over 13,000 miles and includes walls, trenches, and natural barriers. It symbolizes China's strength and history, as well as the challenges of unity and defense. While it served military purposes, it also facilitated trade and the exchange of culture along the Silk Road. Today, it stands as a UNESCO World Heritage site and an iconic symbol of China's enduring legacy.
