How many meters is the wall of Xi 'an?

Rectangular, with wall height 12m, bottom width 18m, top width 15m, east wall length 2590m, west wall length 263 1.2m, south wall length 344 1.6m and wall length 3246544. There are four gates: East Changle Gate, Dingmen in Xi 'an, South Yongning Gate and Beiyuanmen. Each gate consists of an arrow tower and a tower. The existing city wall was built in the seventh to eleventh year of Hongwu in Ming Dynasty (1374- 1378), with a history of more than 600 years. It is the most complete existing ancient city wall building in China.

Some experts believe that the ancient city wall is the most brilliant architectural relic on the ground of the ancient capital of the 13 dynasty. Its value can be said to be unparalleled.

According to accurate measurement, the total length 13.9 12km, height 12m, bottom width 18m and top width 15m of Xi 'an Angu City Wall. Among them, the south wall is 4256 meters long and the west wall is 2706 meters long, covering the imperial city of Sui and Tang Dynasties, extending about1/4 to the east and north respectively; The east wall is 2,886 meters long and the north wall is 4,262 meters long. It was built during the Hongwu period of the Ming Dynasty. The whole city wall, including moat, suspension bridge, lock tower, arrow tower, main building, turret, watchtower, breast wall, crib and other facilities, constitutes a tight and complete medieval castle.

It can be said that every brick on the ancient city wall is like an ancient letter, which is an interpretation of the ancient capital of the 13th Dynasty.

In the second year of Emperor Wendi (582), Yuwen Kai, a famous architect, was the chief architect of the capital construction and began to build Miyagi and Imperial City. Completed in the second year. Then build Guo Cheng. After the establishment of the Tang Dynasty, Daxing City was still the capital and changed to Chang 'an City. In the fifth year of Yonghui (AD 654), Emperor Gaozong appointed Yan Xuande, the minister of the Ministry of Industry, to be responsible for the construction of the outer wall of Tang Cheng and the Jiumen Gate Tower in the East, West and South. The perimeter of the external wall is 36.7 kilometers, the width is 9 ~ 12 meters and the height is more than 5 meters. At that time, the whole city covered an area of 84 square kilometers, with a large scale and neat layout. North-south street 1 1, east-west street 14, the whole city is divided into 109 squares and east-west cities. As Bai Juyi described, "A hundred schools of thought are like Go, and Twelve Streets are like vegetable fields". Tang Cheng, the largest capital in the world, is like the center of world civilization.

At the end of the Tang Dynasty, Huang Chao uprising, 88 1 captured Chang 'an. The government forces in the later Tang Dynasty quickly recovered Chang 'an. In history, "Huang Chao was invincible, burned the palace and fled", almost at the same time, "the loyalist plundered wildly, which was tantamount to a thief, and there were few people left in Chang 'an housing". However, it was Zhu Wen who forced Tang Zhaozong to move the capital. Not only the emperor's officials and gentry migrated, but Zhu Wen also demolished the palace in Chang 'an. The timber removed from the White Temple and the folk Lusheng was transported to Luoyang along the Weihe River and the Yellow River, and the Tang city was reduced to ruins. Han Jian, Chinese ambassador to Chang 'an, rebuilt Chang 'an City; Abandoned the original Guo Cheng and Miyagi, and took the Imperial City Wall as the new Chang 'an City Wall. At this point, the superstar gradually lost his luster. Since the Yuan Dynasty, it has become an important town in the northwest. After the establishment of the Ming Dynasty, Zhu Yuanzhang appointed his second son, Qin Wang Zhu Shang, to guard Chang 'an, and renamed it "Xi 'an". In the third year of Hongwu (1370), Sheng Feng, Duke of Song Dynasty, presided over the restoration of Ancheng and the restoration of the Imperial Capital, which lasted for 8 years. As for the Ming City Wall, the South City Wall and the West City Wall were heightened and thickened on the basis of the Sui and Tang Dynasties Imperial City Wall, extending to the east and north by a quarter respectively; The East Wall and the North Wall will be demolished and built. During the period of Qin Long in Ming Dynasty (1568), Zhang Zhi, commander in chief of Shaanxi Province, built blue bricks for the original Ming city wall. During the reign of Qianlong in Qing Dynasty (178 1), Bi Yuan, governor of Shaanxi Province, renovated the tower, added bricks and improved the drainage system. At this point, the city wall survived.

Xi 'an City Wall was built on the basis of the imperial city of Tang Dynasty during the Ming Dynasty under the guidance of Zhu Yuanzhang's policy of "building high walls, accumulating grain and slowly claiming the throne". Completely around the "defense" strategic system, the wall thickness is greater than the height, rock-solid, and sports cars and drills can be placed on the top of the wall. The city wall includes a series of military facilities such as moat, suspension bridge, sluice building, watchtower, main building, turret, watchtower, breast wall and crib mouth. The city wall has undergone three major renovations after its completion. In the second year of Qin Long in Ming Dynasty (1568), Zhang Zhi, the governor of Shaanxi Province, presided over the restoration, making Tucheng a brick city for the first time. In the forty-sixth year of Qing Qianlong (178 1), Bi Yuan, the governor of Shaanxi Province, presided over the renovation of the city walls and towers. Since 1983, the people's governments of Shaanxi Province and xi City have carried out large-scale repairs to this ancient city wall, supplemented the demolished east gate, north gate watchtower, south gate watchtower and suspension bridge, and built parks around the city, making this ancient building glow with its former style and become a major tourist landscape in Xi.

Looking back at history, the city wall is a traditional defense facility in ancient China. We saw in the Banpo site 6000 years ago that Banpo people dug deep ditches around their homes to guard against the attacks of wild animals and foreign tribes. If banpo village is regarded as the first bud of the city, the deep ditch was the equivalent of the city wall at that time. After people invented the wall-building technology, the city wall was born naturally with the city and became a prominent symbol of ancient cities. According to historical records; "The whale built the city to defend the monarch, and the founding of the country was for life. This city is also the beginning. " This is the late primitive society about 4500 years ago. Xi 'an, as a thousand-year-old ancient capital, has built city walls many times in past dynasties. Most of them were buried by the dust of history. But the Great Wall we saw can still be traced back to the Sui Dynasty in the 6th century.
