The Mysterious and Fascinating Underground Caves of Longyou and Huashan found in China

The Caves of Longyou and Huashan in China:

Longyou Grotto's (Caves of Longyou) and the known ones like Mystical Grottos in Flower Hill ("Mystic caves in the hill of the flower") or Huashan My Ku by its original name in Chinese, are two magnificent complexes of subterranean caves that have been discovered in China in recent years. Not only have archaeologists around the world been surprised by their size and length, their precision, distribution and their meticulous carving in ceilings and walls, which tools were used, but also because they are caves carved by hand in the rock of the that it is not yet known with certainty who were its authors and how they achieved such symmetry, precision and similarity between the different caves.

The caves are located in an area of only 1 km2, very close together, and with an almost identical distribution model. Recent research found that global construction is extremely accurate. The walls that separate a cave from another are of the same thickness in different sections, and in many cases do not exceed 50 cm thick.
According to Yang Hongxun, an expert at the Institute of Archeology of the Chinese Academy of Social Sciences, "There must have been some provision about the size, location and distances between the caves made in advance."

The Caves of Longyou:

It is located in the province of Zhejiang, China, and were discovered by chance in 1992 when a local villager, Wu Anai, began pumping water from a "pond", to discover by surprise that it was a flooded artificial cave. The cave was huge, stretched over 2,000 m2, exceeding 30 meters in height at the highest points of the cave, drained and explored, 24 large underground caves have been found, many of which are found near the village of Shiyanbei, with an area of

more than 30,000 m2. The interior of Las Cuevas de Longyou presents stairs and pillars, sculpted in the rock. The pillars were arranged in line and support the roofs of the caves so that they do not collapse.

Due to the absence of evidence in this sense, all kinds of hypotheses have been made regarding their origin and purpose for which they were built:

• Tomb of some emperor.
• Underground palace
• Mining extraction.
• Lair for the emperor's troops.

The Caves of Longyou are as mysterious as they are fascinating, being one of the largest underground excavations of ancient civilizations.

Huangshan:

Located in the eastern outskirts of the city of Tunxi, Anhui Province of China, it is a complex of large-scale underground chambers artificially built in ancient times, with painstakingly chiselled walls. To date, 36 caves have been discovered.
They were discovered by chance in the spring of 1999 by a local, then giving notice to the Chinese authorities. In 2000, the government of Huangshan Township explored the Huashan site together with experts from Qinghua University and Tongji University.
In the grottos there are tribunes distributed in several levels, ponds and wells full of water and bridges.
Grotto 35, the largest of all, is a kind of underground palace with 18 meters high, 170 meters long and an area of ​​12,000 m2. It has 36 chambers that surround the main hall supported by 26 pillars of standing support of more than ten meters of perimeter and high each, with extravagant forms. To drain it, 18,000 tons of water had to be pumped.

The caves 2 and 35 have an internal surface of 17,400 m2, and the volume of silt and stones taken out of these amount to 20,000 m3.
During the excavation course of the cave some primitive relics were discovered, among them oil lamps and varnished ceramic articles. These last objects have been authenticated by expert archaeologists as products of the Jin dynasty (265-439), which fixes a floor to the antiquity of the caves.

Other evidence that supports this hypothesis is that stalactite stones are seen on a wall of the cave, and in the opinion of experts in geology, a piece of stalactite 5 to 6 centimeters long would need about 1,500 or 2,000 years to form.
The Huashan Caves are located between 29º39 'and 29º47' north latitude, next to the Huangshan Mountain, on the so-called "mystic line" (near the 30º north latitude) because of the number of mystical places that are also located there, such as the Pyramids of Giza (29 ° 59 'N), Persepolis (29 ° 56' N), Ur (30 ° 57 'N), Petra (30 ° 19' N), etc.
Both the Longyou and Huashan caves are amazing because of their grandeur, mystery and beauty. Two underground networks of seemingly interconnected caves, carved into the rock by an ancient civilization that we can barely ask ourselves about, an incredible piece of engineering carved into the rock thousands of years ago. No written records or physical traces of any kind.
