A wall built to last… and last… and last!
The Great Wall of China is one of the most famous structures in the world. It stretches across mountains, deserts, and grasslands, winding its way through northern China. But did you know it took over 2,000 years to build?
Why was it built?
It all started in the 7th century BCE, when small walls were built by different Chinese states to defend themselves from neighbouring enemies.
Later, when China was united under the Qin Dynasty (around 221 BCE), Emperor Qin Shi Huang decided to join these smaller walls together to create one massive defence line. He wanted to protect China from invaders like the Xiongnu, fierce warriors from the north.
Made from dirt and hard work
In the early days, the wall wasn’t made of stone like it is in many photos. Instead, workers used a technique called hang tu, which means “rammed earth.” They packed layers of dirt tightly into wooden frames. It wasn’t pretty, but it was strong!
Later dynasties improved the wall using bricks, stones, and tiles. The most famous version of the wall, the one people visit today, was mainly built during the Ming Dynasty (1368–1644 CE).
Battles and borders
The Great Wall wasn’t just a wall. It had watchtowers, fortresses, and army barracks. Soldiers lived on the wall, ready to defend China from attacks, especially from Mongol forces to the north.
From the Chinese side, the wall was seen as a mighty defence. From the Mongolian side, it was a frustrating obstacle. But sometimes, trade and peaceful exchanges happened too.
How long is it?
That’s a tricky question! For centuries, people guessed how long the wall really was. Some said it was 5,000 kilometres. Others said 10,000! It wasn’t until a modern survey in 2012 that experts measured every known section, including hidden ruins.
The answer? 21,196 kilometres! That’s more than half the way around the world.
A modern wonder
Today, the Great Wall is a UNESCO World Heritage Site and one of China’s top tourist attractions. It’s no longer used for defence, but it’s a powerful symbol of Chinese history and human determination.
While parts of it have fallen into ruins, other sections have been carefully restored so visitors can walk along its ancient stones and imagine what life was like hundreds of years ago.
