7 Strange Discoveries About the Great Wall of China

The Great Wall of China is one of the wonders of the world with a history that dates back more than 2,000 years. While its popularity is as old as time, this eye-popping marvel has continued to grip the attention of tourists globally. The common knowledge about the wall is that it is a military defense project featuring watch towers, garrison stations, and connective walls. However, several strange discoveries that inspire a burning curiosity to visit this monument are always revealing themselves. Here, we look at seven strange discoveries about the Great Wall of China, otherwise known as the world's longest man-made structure.

Plants on either Side of the Wall Are Genetically Different

According to biological science, living things will start displaying diverse traits when separated by natural barriers such as mountains, hills, or glaciers. The Great Wall of China is artificial, but plants on either side of the walls have different genetic components. Scientists from from Peking University, Beijing, confirmed the genetic variability of plants alongside the Great Wall. They experimented with the plants at the Juyongguan section of the wall and compared them with plants separated by natural barriers such as mountains. studying three plant groups. To their amazement, they found that the wall, like a mountain, acted to separate plants genetically.

It Could Take You a Year to Walk the Great Wall of China

Thru-hiking has become popular among many travelers, and the Great Wall of China is one of the top destinations. With a combined length of 13,171 miles, it is almost impossible for anyone to walk its entire length. Most people choose to walk the Ming Dynasty Great Wall, but this section alone stretches continuously for around 5,500 miles. If you were to walk 20 miles every day, it would take approximately 9 months to complete. It could take even longer, depending on weather conditions and how long your cash will last! Despite the nature of the task, a few people have successfully walked the Great Wall, including Dong Yaohui, who did it in 508 days (17 months).

The Walls Cannot Be Seen From Space

Many believe that this colossal structure is visible from space. Unfortunately, this myth fell apart when humans began landing on the moon. Initially, the Chinese rejected the claim that the walls could not be seen from space because it came from Western authors. The Ministry of Education even spread the claim in school books. However, In 2003, the general Chinese public came around after Yang Liwei, the first Chinese astronaut to go to space, confirmed that the wall could not be seen from up there.

The Wall Was Built With Rice

The Great Wall of China was built with stones, sand, bricks, rammed earth, and several other materials, including rice. As impossible and strange as this may sound, it is true. The sticky rice was used to make the mortar that bound the bricks of the Great Wall of China together during the Ming Dynasty (1368 - 1644 AD). The mortar was created by mixing sticky rice flour with slaked lime. The ancient people of the Ming Dynasty knew of the adhesive property of rice long before Modern science. Many years later, modern chemists discovered that rice contained a unique type of polysaccharide known as amylopectin, which gives sticky rice its strong adhesive properties. The sticky rice mortar is still the main binding material within the brick sections of the walls to date. It was so effective that weeds could not grow between the walls, a common occurrence with regular mortar.

The Wall May Be the World’s Longest Cemetary

Human bones were not used to build the walls like rice. However, some estimates of the human toll it took for its construction make the wall the world's longest cemetery. Possibly hundreds of thousands of workers died during its construction and were buried at its foundation. Many of these workers are known to have been convicts who were used to build the wall as punishment since its construction was exceptionally life-threatening.

The Wall Stretches to Mongolia

As the world's longest man-made structure, the Great Wall of China extends beyond China, and into Mongolia. However, the Mongolian part of the wall was largely unknown for many years until a group of explorers spearheaded by William Lindesay rediscovered it in the Gobi Desert. Interestingly, some Mongolians had no idea the wall got to their country or thought it had been destroyed. The Mongolian section of the wall, known as the arc, even predates the main part of the walls built by the Ming Dynasty (1348 - 1644) by about 500 years. Sadly, the Mongolian arc is one of the most dilapidated sections of the wall and receives the least attention, considering that it is just 62 miles long.

The Walls May Disappear in a Few Years

The Great Wall of China stands as a source of national pride for the Chinese people, and it is also evidence of the strength and intelligence of humans. Unfortunately, the walls are not properly maintained. Over the years, about one-third of the Great Wall has disappeared as a result of vandalism and natural causes. Some early walls are currently on the verge of collapse, and without immediate conservation efforts, entire sections may disappear in as little as 30 years.

The Great Wall of China is one of the most popular attractions in the world, receiving approximately 10 million visitors yearly. This is because the wall is a construction wonder with many fascinating features. While the monumental structure is reportedly disappearing due to high tourist traffic, it will continue to stun travelers, archaeologists, civil engineers, and just about anyone with an eye for great things.
