Great Wall Of China: Extra Miles Discovered
The ancient Great Wall of China is almost 200 miles longer than previously thought, according to a new study.
An extra 180 miles of the world-renowned ancient Chinese monument were uncovered after a two-year government mapping study, according to an official report.
The study used mapping technologies such as infrared range finders and GPS devices to show extra portions of the wall - hidden by hills, trenches and rivers - that stretch from Hu Mountain in northern Liaoning province to Jiayu Pass in western Gansu province.
The newly mapped parts of the wall were built during the Ming Dynasy to protect against northern invaders.
