Qin Shihuang built the Great Wall to defend against foreign enemies. When was it built?

In the thirty-third year of Qin Shihuang (2 14 BC), he sent general Meng Tian to drive the Xiongnu in the north, from Lintao (now Minxian County, Gansu Province) in the west to build the Great Wall in Liaodong in the east to stop the Xiongnu from going south, which was called Qin Changcheng in history. Guyuan area was actually built on the basis of Qin Changcheng in the Warring States Period, and it runs across Xiji, Guyuan and Pengyang counties from east to west.

Great Wall Ruins of Qin Dynasty

In Baotou, besides the Great Wall built by the earlier King Wuling of Zhao, there is also a relatively complete Qin Changcheng.

In 2 15 BC, Meng Tian, the general sent by Qin Shihuang, led 300,000 troops to attack the Xiongnu in the north and took the land of Henan. In order to prevent the invasion of northern nomads, the Great Wall of Wan Li was built from Shanni County, Gansu Province in the west to Liaodong County, Liaoning Province in the east. After extending from Ningxia to Inner Mongolia, from Langshan to the east, it passes through Xidoupu, Yin Hao and Damiao Township in the north of Guyang County.

The total length of Qin Changcheng in Baotou City is about1.20km, and most of it is built on the north slope of the mountain. It is dangerous to rely on the mountain, and it is possible to rely on the mountain. Most of the valley passes and Pingchuan areas are built with rammed earth, and most of the mountains are built with stone or mixed earth and stone. Generally, Stone Great Wall Scienc Spot remains are well preserved, and the existing external walls are generally more than 4m high, 4m wide at the bottom and 2m wide at the top. Standing on a high place, you can also see the Great Wall climbing up the mountain, which looks like Youlong. Every once in a while, you can tell the remains of ancient bonfires and fortress cities. There are 8-9 ancient city ruins inside and outside Qin Changcheng in Baotou, among which pottery pieces from Qin State to early Western Han Dynasty can often be found.

Qin Changcheng not only has its own style in construction methods, but also has certain characteristics in the construction of defense facilities. Qin Changcheng is famous for its magnificent stone buildings, which were used in the Han Dynasty. It is a treasure of our Chinese nation, a miracle in the history of world architecture and a symbol of our glorious history and culture.
