The Most Mysterious Cave in The World

Longyou Caves Mystery - For thousands of years, the Longyou Caves remained lost to time and history. No one even knew that such a cave existed. But all that changed one day when one curious local of the Shiyan Beicun village decided to put a popular legend to the test. #longyu #cave #mystery

dude, these filters youre running while trying to show the pictures.. dumb. don't do that. Its awful.

[JustinPogue]

I don't think the video mentioned one of the most mind-bending aspects of this, which is that several of the 24 known caverns are super-close to each other to where the carved-out chambers are separated by uncarved rock wall that is only a few inches thick. This makes me question the cistern theory. Why would they need the chambers to stay apart if it was water storage? If it WAS cisterns, then wouldn't boring chambers so close to each other in different caverns put the whole project at risk, due to the weight of the water against rock that you've thinned out? Anyhow. Each cavern on its own is a marvel. 24 (or more) of them in a planned architecture is beyond marvelous and creeps right up on the uncanny.

In India there are water reservoirs that have stairs so people can reach the water at whatever level it is at. So that supports the cistern hypothesis.

I think the grove marks would have served two purposes: 1) increase the surface area of the walls and ceilings they've been carved into to increase strength of those structures; 2) the groves might serve as crack stops. If a crack were to form on the surface of the wall or ceiling, it wouldn't propagate very far before running into a ridge, which would stop it's progression.

Why does everyone avoid showing the bas relief sculptures on the walls ?
They get all squishy about the tool marks … but never show in detail the pictures the builders cut into the walls .

[origrockart]

It's baffling to me, that people still think these megalithic marvels were somehow constructed by the primitive ancestors of our current civilization. Many of which, we still can't replicate today. I did still enjoy the video and the curiosity it may ignite. Thank you for taking the time to create it 🙏

[TheFixsInn]

Two things didn't get mentioned...

1. What are the acoustic properties inside each complex. It could have a function similar to the grand gallery in the pyramid. Those carved lines could be to tune or resonate certain frequencies. Maybe nobody resided in there because it could have had an industrial use, rather than a shelter.

2. No mention of the artwork on the walls you keep showing thru out your presentation. What type of animals are being depicted. What type of clothing is being worn. Clues to time periods.

Keep up the good work!

I was raised in the suburbs of Johannesburg, and in the 1960's, an underground reservoir was built about 3 or 4 miles from where I lived. I couldn't help thinking about it on seeing this video, because it was so similar. It was modern, so it was built with concrete, of course, and the walls were flat, not ridged, but it was huge, and fascinating to me, because I made recordings of its accoustics. I could sing an arpeggio - C, E, G, C - each note for about a second, and the echo produced the arpeggio chord, which was audible for more than a minute.

What I wanted to say about it is that it was not built for the public to see - I saw it during construction, because there was a big hole in the side of the hill that it was built ionto, where lorries (trucks to the American readers) could go in and out to carry the spoil away - and I'm sure that there were plans lodged somewhere in some company archive - but if it was discovered by some historian or archiologist in 1, 000 years' time, it's quite likely they would not find any record if it. If the Longyou caves had been built as a residence for an emperor, or as something to attract tourism, then there would certainly be records - but a water reservoir? I don't find it surprising at all that there are no records if, indeed, that was their purpose.

[ericnealy]

Sounds like you're telling half of the story.... Why are you not showing what's on the walls.

[athena_the_hun]

You keep talking about sophisticated works - but mentioning that the people who did it are primitive. These people were more sophisticated that we are ❤

[BBDA-CLEAR]

Unfortunately you are all over the shop. They are not chisel marks on the roof and the walls, try machine marks, and the reason the roof is rippled
Was because they desired that affect through the machine they used. The reason no one heard about the Longyou caves was the fact that it probably goes back 10, 000 years . At least 3 1/2 million tons removed and completely disappeared. And your hypothesis is chisel marks.😊

[eckelolini]

Yes. I think you missed the fact that water storage facilities like this one had stairs so that the water would be accessible no matter how low the water level got in there.

[jdp]

Electricity was discovered, not invented.

[SevenHerons]

Cisterns. The markings on the wall are for water level, obviously. Either for irrigation or drinking purposes, you need to plan ahead. Especially in times of drought.

[sheldonwheaton]

Electricity was never invented. It was harnessed?

[billstapleton]

During the Younger Dryas period Meteorites were striking the earth. The people at the time, started going underground. You find over 36 underground cities in Turkey. I believe there are more underground cities around the world.

[simonallan]

Longyou caves were obviously made by an ancient advanced civilization, so why would they be using primitive lighting methods?

[franceslynch]

The Han dynasty doesn't have any records because the Han dynasty had no role in building it. I think they caves are pre flood, well pre flood. As for the tool marks, they indicate what equipment was used to carve them. This was a mechanized effort, NOT done by hand IMO.

[arsenelupiniii]

The ground water level has for sure come up in the last 13, 000 years. Those are machine marks on the cave walls, large, heavy machines.

Megalithic civilization built these, modern history denies their existence, but their buildings are here and will last longer than our expert's explanations. Human history goes far more back and far more different than what today's experts try to sell us!
