Great wall of china stretching

The Great Wall of China, one of the world's most iconic structures, stretches for thousands of kilometers across mountains and deserts.

About this subject

The Great Wall of China is a series of fortifications built over several centuries, starting in the 7th century BC, to protect Chinese states and empires from invasions. Its official length is 21,196 kilometers, including branches and natural barriers. The most famous sections, built during the Ming dynasty (1368, 1644), use bricks and stone, while older parts are made of rammed earth.

Contrary to popular belief, the wall is not a continuous line; it has gaps and multiple branches. It crosses provinces such as Beijing, Hebei, and Gansu, with elevations ranging from 0 to 2,000 meters. Construction involved soldiers, peasants, and prisoners, and it is estimated that hundreds of thousands of workers died during the works.

The wall holds immense cultural and historical value, symbolizing resistance and national unity. It was designated a UNESCO World Heritage site in 1987 and is one of the most visited tourist destinations on the planet. Despite its fame, large sections are in ruins due to erosion and human activity. Interestingly, the myth that it is visible from space is false; it can only be seen under ideal low-orbit conditions.

Today, the wall remains a global icon, inspiring films, literature, and art. The Badaling section near Beijing is the most restored and accessible to tourists, while others like Jiankou offer wild and challenging views for adventurers.
