Walled area in the city of Xian. A few hundred yards of the Little Goose Pagoda, there is the South Gate of the Great Wall of Xian. Surely the most important. The Wall of Xian was built during the Ming dynasty, between 1374 and 1378; on the ancient Forbidden City in the Tang. It is a rectangular wall with 3, 4 kilometers from east to west and 2, 6 north to south. She is twelve feet tall and its base width varies between 15 and 18 meters, and at its peak between 12 and 14 meters.
