The Great Wall of China, the Great Wall of Gorgan - scientists have long since figured out who and when was involved in the construction and restoration of grandiose structures. But when and who built the third Great Wall - Kelasur in Abkhazia - is still unknown.❕

This "baby" is only 160 km. long. Till now have survived about 200 towers, each of them 8 to 15 meters high.

This grandiose fortification is considered one of the most mysterious and controversial structures of the Caucasus. Scientists have been studying the wall for more than a century, but so far they have not been able to answer the question "who and when?", the range of dates of construction is from the 6th to the 17th century.

To miss an entire fortress in the annals of history - it takes some skill. There must be evidence of the construction - the allocation of money from the treasury, the name of the ruler who started the construction of the century, the name of the opponents, records of sieges and attacks of the fortress by enemies (not

As stated by experts, in nature can not exist fused granite, otherwise, when heated strongly, it breaks down into sand, but at this point, the rule does not seem to apply.

Because of global warming, Antarctica reveals the secrets stored in its snow. On the surface of Antarctica, the melting ice revealed a huge face. The sight has caused indescribable excitement. The face looks like a huge ancient sculpture, not shown before on Google Earth maps.

And indeed in this picture we can see the clear contours of one eye, nose and mouth. Many people say that this picture is an ancient artifact. There are also skeptics, who argue that such a drawing could have been made by the winds, because nature is one of the best artists.So what is natural or artificial?

By the way, you can see for yourself that there really is a face. Just go to these coordinates

According to history, in the 10th-14th centuries more than 2,500 Buddhist pagodas and temples were built in Myanmar, which successfully survived the world wars. But in 2016 there was a major earthquake📜

Next comes a story in the spirit of Palmyra, destroyed by terrorists: the collapsed brick stupa is pierced with rebar. What was brickwork reinforced for in the 10th century? Where did advanced metallurgy come from at the time?

Roman heating worked like this: hot gases were vented into cavities in the walls and floor, heating the dwelling, only then leaving through a chimney out of the house. But this system consisted of fireclay bricks, found by archaeologists.

The problem is that fireclay bricks are fired at temperatures of 1.300-1.500 ° C in rotary kilns.

No idea, how could an ancient Roman get it, if firewood produces a maximum of 900°C, and coal - 1,200°C? Not enough temperature! And it became possible to get this kind of temperature closer to the 15th century. The Romans just didn't know they didn't have the right technology. Or the dating is wrong by a thousand and a half years.

With millions of tons of hand-carved stone, the Egyptians had to make mistakes sooner or later. But the stelae, sarcophagi and blocks are perfectly chiseled, the angles are accurate to 1 degree, and the grinding has been preserved for thousands of years. But some of the blocks have marks on them that look like a bolt cutter. Scientists try to ignore them or give dubious versions about copper and abrasive📜

How did the chisel have to slip off to draw long, even lines?

Qasr al-Farid, Saudi Arabia

There is a temple of some kind carved into the "pebble". It is said to be a tomb. It is not clear how or with what it was done.

If you think that the Trinity is an exclusively orthodox object of veneration, you are deeply mistaken❕

"The Buddhist triad" is an ancient image of the Buddha himself, the Buddha of the future, and the Bodhisattva of Light. Such images and triads of deities are far from uncommon in various religions. And the newly born Christianity has only combined the most successful ideas of the past.

Dwarves, fairies, and subterranean dwarfs really existed before the 18th century🤔

The Skara Brae settlement was dug up in Scotland after a hurricane in the 1920s. The settlement was founded before 3100 B.C. and had existed for about 600 years. The stone walls, beds, ceilings and doorways were designed for occupants up to one meter tall.

In size, the people copied Egyptian, Italian and Slavic dwarfs, and in Britain itself gnomes, elves, fairies and leprechauns make up a huge part of the cultural heritage. More recently, the archaeological part as well📜

Giovanni Battista Fiorini's 1563 fresco depicts giants and men. If historians call the drawings of giants "the gods and nobles painted this way," does that mean there was one slave for the whole city? Or is this a city of gods?

In any case, these giants look harmonious against the background of ancient architecture, but the little man in height looks more like a modern man🤔

Three ingredients are needed to make gunpowder: saltpeter, sulfur and coal. There has always been coal in China. Until the 18th century, native sulphur was only available at the mouth of the volcano Etna, in Sicily. The nearest deposit of saltpeter was on the island of Ceylon. In the Mendeleev Table, only saltpeter and sulphur may be components of black powder, while all other explosives are explosive, which would blow any cannon to pieces.

How could China invent gunpowder with only 1 of 3 components?

Ancient people had the technology to make flexible and unbreakable glass

References to such glass can be found in Pliny the Younger, Petronius and Dion Cassius. They tell of an alchemist who surprised the Emperor Tiberius.

Tiberius demanded to know the secret of creating flexible glass and ordered the alchemist to be executed. The emperor feared that such glass would affect the value of gold and silver.

A similar glass and plastic analog was recreated by our contemporaries thousands of years later.

Everyone knows that the combustion engine has a very low efficiency of about 23%. An electric motor has 90-95% efficiency. And knowing this, engineers and scientists continued to improve gasoline engines. As a result, the future is in electric motors🤔

The technology has been known for a long time. But progress had to be stalled in the name of super profits from oil.

About lost technology: in 1920, engineer Royal Rife created the world's first ultraviolet microscope with a 50,000x magnification that allowed a live virus to be seen. Fifteen years later, Rife created a frequency generator - by resonating with the frequency of the virus, the radiation struck the pathogenic microflora without injuring the surrounding tissue.

Fourteen fully documented cases of complete healing of cancer patients and the "American Medical Association" achieved the cessation of research in this area, the use of his generator in the United States was banned.

Experiments with the frequency generator were repeated by our contemporaries, confirmed the simplicity and effectiveness of the method to combat viruses and pathogens, but for some reason official medicine again refused to recognize the development.

The Barabar cave system in India. 200 to 300 B.C.

The caves are carved in gneiss, as hard as granite. Vaults, floors, and ceilings are polished to a shine. The acoustics and ventilation of the caves are ideal. There are reservoirs for water and hermetic closing of the doorways. There is a version that the caves were used in ancient times as a bomb shelter. The vaults are capable of withstanding a nuclear strike. Ancient skeletons with high levels of radiation are often found in the vicinity.

Petroglyph in Colombia

Located in the equatorial region of the country. Carved in solid granite. According to local legends, this is the exact place where from "the Milky Way the first people arrived in a canoe pulled by an anaconda. Man woman and three plants: yucca, coca and yage"...🤔
