The Great Wall of China, one of the most awe-inspiring man-made projects in the world, lies across the northern part of China like a great sleeping dragon, winding its way through China's vast northern territory. With a history of over 2,500 years, the Wall attracts visitors from all over the world. In 1987, Great Wall was listed on UNESCO's World Heritage List and selected as one of the new Seven Wonders of the World in a global poll announced on July 7, 2007. It is often said that "If you haven't climbed the Great Wall, you haven't seen China." Most people in the world have seen photos of the amazing construction, but photos are poor imitations of the beauty and grandeur. No China tour is complete without seeing the Great Wall. Visiting it is the experience of lifetime.
