Visiting the Great Wall of China in 2008 was one of the highlights of my travel adventures. The Great Wall stretches 6300 kilometers (3,915 miles) in length. It is not one continuous wall but made of many different sections. If you measured the length of all the different sections , . distance would be more like 22,000 kilometers (13,670 miles) The widest section is about 9 meters (30 feet) and the first parts of the wall were built over 2000 years ago. Definitely hope to return and see it with new eyes.
