Great Wall of China

The Great Wall of China (traditional Chinese: 萬里長城; simplified Chinese: 万里长城; pinyin: Wànlǐ Chángchéng, literally "ten thousand li long wall") is one of the most famous structures in the world. It is a series of fortifications built across the northern borders of ancient Chinese states and Imperial China. The wall was created to protect China from various nomadic groups who lived on the Eurasian Steppe.

Construction of the first walls began as early as the 7th century BC. These early walls were later connected and expanded during the Qin dynasty. Over many years, different Chinese rulers added to the wall. The sections most people see today were built during the Ming dynasty, which lasted from 1368 to 1644.

The Great Wall includes many features to help with defense, such as watchtowers, places for soldiers to stay, and ways to send signals using smoke or fire. It also helped control who could enter or leave China and collect taxes on goods traveling along the Silk Road.

The entire wall stretches for thousands of kilometers, from Liaodong in the east to Lop Lake in the west. It is so long that it can sometimes be seen from space! In 2007, the Great Wall was chosen as one of the New 7 Wonders of the World. Today, it stands as an amazing example of ancient engineering and remains a popular place for people to visit and learn about history.

Names

The Great Wall of China has had many different names throughout history. In Chinese, it is often called the "Long Wall" and was mentioned in ancient records. The longer name, "Ten-Thousand Mile Long Wall," comes from old descriptions but does not mean it is literally ten thousand miles long — it is a way of saying it is extremely long.

Over time, different Chinese dynasties used various terms to refer to their border walls. Today, both in Chinese and English, it is commonly known as the Great Wall of China. Some parts of the wall are nicknamed the "Wall of Genghis Khan," though he did not actually build them.

History

Main article: History of the Great Wall of China

The Chinese began building walls as early as the 7th century BC to protect their borders. During the time when many small states fought for power, called the Warring States period, each state built its own walls for safety. When the state of Qin united China in 221 BC, its leader, the First Emperor, connected these walls to form a single great barrier against northern invaders like the Xiongnu people.

Later dynasties, such as the Han, Northern dynasties, and Sui, also repaired and expanded the wall. During the Ming dynasty, the wall was rebuilt with stronger materials like bricks and stone, and many watchtowers were added to guard against Mongol raids. Even today, parts of these walls still stand as a reminder of China's rich history.

Course

The Great Wall of China is made up of many different parts, including walls, trenches, and small forts. In 2012, experts in China counted many pieces of the wall still left today. They found over 10,000 sections of wall, more than 1,700 trenches, almost 30,000 buildings, and over 2,000 places where walls pass through.

The Ming Great Wall, built during the Ming dynasty, is one of the most famous parts. It stretches for about 8,850 kilometers. Parts of it go through deserts and mountains, and some sections near Beijing are visited by many tourists each year. One well-known piece is the Badaling Great Wall, which was the first part opened to visitors. Other famous spots include Jinshanling, where the wall climbs steep hills, and Shanhai Pass, called the “First Pass Under Heaven” because it marks the traditional end of the wall.

Characteristics

The Great Wall of China was built using different materials over time. Early walls were made from rammed earth, stones, and wood. Later, during the Ming dynasty, bricks became a main building material because they were easier to work with and stronger than earth. Stones were also used, especially for foundations and important parts of the wall.

Guards walked along special pathways called battlements on top of the wall to watch for danger. Tall signal towers were placed on high points so messages could be sent between army units. Near the wall, soldiers had barracks, stables for horses, and storage for weapons.

Condition

Parts of the Great Wall of China near Beijing and popular tourist spots have been carefully preserved, but in many other places, the wall is in poor condition. People have sometimes taken stones from the wall to build houses and roads, and some parts have been damaged by graffiti and vandalism. Valuable bricks from the wall have even been stolen and sold.

In 2012, a report said that about 22% of the Ming Great Wall had disappeared. In some areas, strong winds and sandstorms are causing the wall to wear away quickly. Unfortunately, some people have also damaged parts of the wall for construction or other purposes, which has caused lasting harm to this important historic site.

Visibility from space

Many people believe the Great Wall of China can be seen from space with the naked eye, but this is not true. It cannot be seen from the Moon, which is much too far away. Even from low Earth orbit, it is very hard to see unless conditions are perfect. Some astronauts have said they saw it, while others, like Yang Liwei, China’s first astronaut, could not. Photos taken from space often show the wall only faintly, and sometimes other objects are mistaken for it.
