The Great Wall is even longer than we thought it was:

"The Great Wall of China is even greater than once thought, after a two-year government mapping study uncovered new sections totalling about 180 miles, according to a report posted on the website of the country's national mapping agency.

Using infrared range finders and GPS devices, experts discovered portions of the wall concealed by hills, trenches and rivers that stretch from Hu Shan mountain in northern Liaoning province to Jiayu Pass in western Gansu province, the official China Daily reported on Monday.

The newly mapped parts of the wall were built during the Ming dynasty (1368-1644) to protect China against northern invaders and were submerged over time by sandstorms that moved across the arid region, the study said."
