Dear Bruce,
Greetings from Sophie, tour advisor in Top China Travel!
Thank you very much for your questions.
The Great Wall is a symbol of China. It was originally built from 215 B.C. in Qin Dynasty in China to prevent the enemies from Northern China. After that, every dynasty built and repaired the great wall to prevent enimies.
Nowadays, the great wall which we see is from Ming Dynasty because the older great wall is too old to exist.
The Ming Great Wall starts from Shanhaiguan Pass in Liaoning Province in the east and ends at Jiayuguan pass in Gansu Province in the west.
Generally speaking, when people visit to Great Wall of China, people often choose to visit the sections surrounding Beijing, such as Juyongguan Great Wall, Badaling Great Wall, Mutianyu Great Wall, Jinshanling Great Wall, ect.
