Great Feats of Engineering: The Great Wall of China

In our last post in the ‘Great Feats of Engineering’ series we looked at The Trans-Siberian Railway, which is a network of railways that connect Moscow with the Russian Far East and the Sea of Japan. For the next instalment in this fascinating series that looks into some of the most extraordinary accomplishments of engineering, we will be looking at The Great Wall of China.

Great Wall of China

The Great Wall of China is the world’s longest wall and the biggest ancient architecture. It stretches across North China from east to west for over 5500 miles.

Originally, the wall was built in the fifth century B.C as a defensive structure, to protect against raids and invasions. However, the best known and best preserved section of the wall was built in the 14th-17th century A.D.

How it came to be?

Some of the Great Wall was first built by princes and overlords sometime in the 7th Century BC – as a boarder defence when China was divided into many small states. However, the big changes came later on.

In 221 BC, King Zheng of Qin conquered the last of his enemies and unified China – becoming the First Emperor of the Qin Dynasty.

He wanted to prevent the resurgence of feudal lords, so he ordered the destruction of the sections of the walls that divided his empire among former states. However, he still wanted to position the empire against the Xiongnu people from the north, so he ordered the building of new walls to connect the remaining fortifications along the empire’s northern frontier.

How was it constructed?

Builders had to use local resources, as transporting heavy materials was proving to be too difficult. Stones were used from the mountains over mountain ranges, and rammed earth was used for the construction in the plains.

Later on in the Ming era, the construction was stronger and more elaborate due to the use of bricks and stone instead of rammed earth.

Functions of the wall

The Great Wall of China has been used for a number of different purposes over the years. These include:

  • Military uses – defensive works such as forts, passes and beacon towers were built across the wall. These were to house auxiliary soldiers and to store weapons.
  • Infrastructure and Development – it provided protection to economic development and cultural progress. It was also used to safeguard trading routs such as The Silk Road.
  • Tourist – a few sections of the wall have become one of the greatest tourist attractions of all time.
