Overview of the Great Wall of China
The Great Wall of China, one of the Seven Wonders of the Modern World, stretches across northern China, built to protect against invasions and facilitate trade control. Spanning over 2,300 years of history, it’s a testament to Chinese engineering and cultural resilience, attracting over 10 million visitors annually.
Key Facts About the Great Wall
1. Length and Scale
The Great Wall is 21,196 kilometers (13,171 miles) long, according to a 2012 survey by China’s State Administration of Cultural Heritage. It spans 15 provinces, with sections varying from 4 to 16 meters in height and 4 to 5 meters in width.
2. Historical Timeline
Construction began in 221 BC under the Qin Dynasty, unifying earlier walls. The Han (206 BC–220 AD), Northern Wei (386–534 AD), and Ming Dynasties (1368–1644) expanded it, with the Ming building the most enduring stone and brick sections.
3. Purpose and Function
Built to defend against Mongol invasions, the Wall also served as a border control, managing trade along the Silk Road and regulating migration. Watchtowers, spaced every 200–300 meters, facilitated communication via smoke signals.
4. Construction Materials and Labor
Materials included tamped earth, wood, bricks, and stone, with sticky rice mortar used in Ming sections for durability. Over 1 million workers, including soldiers, peasants, and prisoners, labored, with an estimated 400,000 deaths during construction.
5. Preservation Status
About 30% of the Wall is in poor condition or has disappeared due to erosion, vandalism, and urban development. Restoration efforts focus on sections like Badaling and Mutianyu, with $1.5 billion invested since 2000.
