Great Wall of China

The Great Wall of China or Great Wall is a building that is 21,196 kilometers long. It has a height of 8 meters and measures 4 meters wide.

It starts in Gansu province and ends in the Gulf of Bohai.

Given its architectural grandeur and history, it is considered one of the Seven Wonders of the Modern World. For this reason, it is one of China’s top tourist attractions, receiving over 4 million visits a year.

The Wall of China is so long that it can appear on radar images taken in low Earth orbit. But, contrary to what has been reported by many, it can not be seen from the moon.

The Great Wall crosses valleys and mountains across 11 provinces of the country and the autonomous regions of Inner Mongolia and the Hui Nationality of Ningxia.


The Wall of China was built to consolidate the empire of Qin Shihuang. Before gaining control of China, the Chinese states each had their own wall.

To show that China was one, the first Chinese emperor – Qin Shihuang – ordered the construction of the Great Wall, which was done over four dynasties: Zhou (1046 to 256 BC), Qin (221 to 207 BC), Han (206 BC to 220 AD) and Ming (1368 to 1644).

It had as objective to protect the country from invaders and also occupy men rioters and soldiers with the end of wars were without work.

About 300,000 of these workers, who totaled over one million men, died as a result of working conditions.

The work was only completed about 2200 years ago, that is, hundreds of years after it began, because it was stopped for some time.

In the Han Dynasty, Emperor Liu Bang used construction not only as a military protection, but also to regulate the silk trade.

Throughout the dynasties, the building was repaired, but no maintenance effort was as strong until 1980.

Despite this, the Great Wall is deteriorating. This is because a bad restoration of its construction is made whose materials used vary according to its location. It can be said that part of it is made of blocks of stones, mud and bricks.

Another factor in its ruin is the depredation and theft of bricks. According to scholars, about 14,000 kilometers may be at risk.

The wall connects almost a thousand forts. Therefore, along it there are windows and trunk (spaces where cannon mouths are placed). There are also platforms that served to attack enemies and almenara towers from which communications were made between the military.
