1. The tomb of Wu Zetian is called "Ganling". The site of Ganling is exquisite: Ganling is located on Liangshan Mountain, 6 kilometers north of Ganxian County, Shaanxi Province, and 76 kilometers away from the ancient city of xi 'an. It was built in 684 AD, and it took 23 years for the project to be basically completed. Liangshan is a naturally formed limestone peak, with three towering peaks, the highest in the north, with an altitude of 1047.3 meters, and the lower in the south, with an east-west direction. At that time, the masses called it "Nitou Mountain". Looking from east to west of Ganling, Liangshan is like a woman lying on her back, with the north peak as the head and the south two peaks as the chest. People often say that it is a wonderful symbol of Empress Wu Zetian. In the Tang Dynasty, Feng Shui experts and Mr. Feng Shui believed that Liangshan was beneficial to the hostess. So Wu Zetian chose Liangshan as her husband Tang Gaozong and her "eternal domain" after a hundred years.
2. The dry tomb is a solid tomb: because the dry tomb was built on the mountain, it was dug in the middle of Liangshan at an altitude of 1000 meters. The mountains are all hard bluestones, so it is very difficult to steal this stone tomb. Even according to the present grave robbing technology, it will take at least 1~2 months to open the grave. It's too long for a grave robber to be caught before opening the stolen hole.
3. When Ganling was built, it was in the heyday of the Tang Dynasty, with strong national strength, grand cemetery scale and magnificent architecture, and was called "the crown of emperors' tombs". At the beginning of the Tang Dynasty, Li Shimin, Emperor Taizong, learned from historical lessons that there was no immortal country and no grave to dig. Starting from Zhaoling, he and his eldest grandson created a burial system with mountains as the tomb, which was designed by famous artists Yan Lide and Yan Brothers at that time. Tombs are made up of buildings and sculptures, and they are scattered on the mountains with the trend of "Dragon Board Phoenix".
4. The dry tombs of Tang Gaozong and Wu Zetian developed and perfected the shape of Zhaoling. The cemetery is modeled after Chang 'an, Tang Dou, and is divided into Imperial City, Miyagi City and Outer Guo Cheng. The north-south main axis is 4.9 kilometers long. According to documents, there are two walls in Ganling and four gates in the inner city, namely Dongqingmen, Nanzhuquemen, Xibaihumen and Beixuanwumen. According to the investigation by archaeologists, the inner city of the cemetery is square, with the length of the north-south wall1.450m, the length of the east wall1.582m and the length of the west wall1.438m, with a total area of about 2.3 million square meters. There are many magnificent buildings in the city, such as 60 courtiers, such as the memorial hall, wing, cloister, Quelou and Di Renjie, as well as the ancestral temple and Xiagong.
5. From the theory of geomantic omen: After her death, Wu Zetian asked Yuan Tiangang and Li, the famous magicians in the ruling and opposition, to choose a geomantic treasure house for the emperor. Two people travel around Kyushu respectively, and when they come back, they all say that they chose Liangshan in Qi Hao County and Jing 'an County. Wu Zetian sent envoys to inspect. At the top of Liangshan Mountain, Yuan Tiangang said that he had buried a copper coin here, and Li said that he had nailed a nail here. Digging the ground, Li's nail was just inserted in the copper square hole buried by Yuan, and everyone present applauded in surprise. So Wu Zetian chose the mausoleum site in Liangshan, which is now the dry mausoleum. As far as geomantic omen is concerned, Ganling has surpassed all the imperial tombs in the Tang Dynasty.
Wu Zetian's mausoleum was hacked to death by the sword of the cold weapon era and shelled by the machine gun of the hot weapon era. 1200 years, there were as many thieves with names as 17, including 400,000 at the most, and Liangshan, where Gan Ling was located, was almost dug away. However, Wu Zetian's Gan Ling was able to live alone. These reasons have played a great role.
Extended data
Ganling is located in Liangshan, 6 kilometers north of Ganxian County, Xianyang City, Shaanxi Province. This is the tomb of Tang Gaozong Li Zhi and Wu Zetian.
Ganling was built in the first year of Tang Guangzhai (684) and in the second year of Shenlong (706). Adopting the construction method of "taking the mountain as the mausoleum", the mausoleum area is modeled after the capital Chang 'an. In addition to the main tomb, there are seventeen small tombs buried in Ganling with other royal family members and heroes. Ganling is the best preserved of the eighteen tombs in the Tang Dynasty, and it is also the only tomb in the Tang Dynasty that has not been excavated. 196 1 On March 4th, Ganling was announced by the State Council as the first batch of national key cultural relics protection units.
Ganling is a masterpiece of the memorial architectural project of "Taking the Mountain as the Mausoleum" in Tang Dynasty, and it is the burial tomb of Tang Gaozong and Wu Zetian. After the Qin and Han Dynasties, the emperor and queen were not buried together, but the "double saints" tomb of the Ganling couple was unique. Ganling is also the only imperial mausoleum in the Tang Dynasty that has not been stolen for thousands of years. Its underground tunnel number lettering masonry has been found, and thin waist iron bolts and tin iron ingots have been unearthed, which has unique value that ordinary tombs do not have.
