The Great Wall of China was built and rebuilt over many centuries.

The Great Wall of China was built and rebuilt over many centuries by successive Chinese dynasties, primarily as a defensive fortification intended to protect against invasions and raids from northern nomadic groups. Rather than being a single continuous structure built at one time, it actually consists of numerous sections constructed, modified, and reinforced across different historical periods. Today, the wall stands as one of the most iconic symbols of Chinese history and engineering achievement.
