When Was the Great Wall of China Completed?
Quick Answer
The Great Wall was built and rebuilt over roughly 2,000 years, from the 7th century BCE through the Ming Dynasty; the most iconic stone-and-brick sections were completed during the Ming era (1368-1644).
The Full Story
The Great Wall is not a single structure but a series of walls and fortifications built by successive Chinese dynasties. The earliest walls were erected by individual states during the Warring States period (7th-3rd centuries BCE). Emperor Qin Shi Huang connected and extended these walls after unifying China in 221 BCE, creating the first "Great Wall" using rammed earth — hundreds of thousands of labourers, many conscripted or enslaved, died during construction. The Han Dynasty (206 BCE-220 CE) extended the wall westward to protect Silk Road trade. After centuries of neglect, the Ming Dynasty (1368-1644) rebuilt the wall with stone, brick, and watchtowers — these are the iconic sections near Beijing that tourists visit today. Including all historical sections, surveys in 2012 measured the total length at about 21,196 km, though much of the earlier rammed-earth construction has eroded away.
