The Great Wall is one of the seven wonders of the world. It runs in sections over a very long distance across China.
The wall is also referred to as ‘Long Wall’ as it is over 21,196 km/13,171 miles long. It was built with stones, bricks and tiles, earth as well as of wooden material. The wall was completed in 1644, but it took more than 2,000 years to build.There are more than 20,000 watchtowers along the wall as it was built to protect the country against invasions from nomads and enemies and to make it easier to collect duty for goods that were transported along the Silk Road.
Today the wall is the most popular tourist attraction in China with more than 10 million visitors per year. Contrary to popular belief the Great Wall cannot be seen from the moon!
