Many dams built in the 20th century are cracking and falling apart. They regularly have to be repaired, rebuilt. It's funny, but large institutions worked on the structures.

What does it take to build a dam that will stand as solidly as the Tibi Dam? Imagine, Tibi has been holding back the river for five centuries.

Has the quality of our education declined? Or are today's engineers all hackers?😁

Why were giants depicted in drawings and frescoes?🤔

Scholars explain that the nobility and the gods were portrayed as tall to emphasize their status.

According to this logic, in Giovanni Fiorini's fresco from 1563 one slave for the whole city? 😂

But why were grandiose structures built with doors designed for a height of 3.5m or more?

There has long been evidence of giant-sized peoples living on the planet in the Americas, Russia, and Africa.

The Spanish Tibi Dam, built in 14 years

An arched and gravity block dam is located at the intersection of the river with a rocky ridge. Design institutes work on such structures. Imagine how much design work, calculations, money, and people it took to cut, move, and lay the blocks under the pressure of the river in 1580?

Spaniards with hammers erecting hydraulic structures on which entire institutes are working in the 20s

Vatican Library📜

It is one of the most guarded facilities in the world: its protection is more serious than that of any existing nuclear power plant. In addition to numerous Swiss guards, the library is guarded by state-of-the-art automatic systems that form several layers of security.

The secret archives of the Vatican became known in 1611 under Pope Paul V. Only a limited number of people could get in. Some scientists with a letter of recommendation can get into the holy of holies, but the entrance is regulated and allows two people per year. At the same time, the entrance to the archive does not imply free movement and access to any documents. The visitor indicates the topic of interest, and the appropriate literature is selected.
This closed nature raises questions and gives birth to theories about what the Vatican archives actually hold

Probably secret Vatican archives contain evidence of real human history🤔

French stones with ancient sharpening marks are identical to the Swedish ones🤔

While in Sweden it has been suggested that these are traces of sharpened swords or axes, the French traces date back to the Neolithic period. A period when there were no tools stronger than stone tools.

Interesting: the finds are identical, but the versions of their origin are different.

In the center of Sri Lanka on a huge stone plateau is the ancient city of Sigiriya, built about 1500 years ago by King Kassapa 1

All the buildings in it are made of bricks, which were delivered to a height of 200 meters. How? The stairs to the city were built just recently, and the ascent to the plateau and without hundreds of tons of bricks was as difficult as possible.

Why build a city in such an inconvenient place at all, especially for the ancient people? Unless such a height was their only escape route 🤔

Before Our Time📜

Fort Louvois

It was built on the islet of Chapoux between 1691 and 1694, during the reign of Louis XIV. The fort is located about 400 meters from the shore, opposite the citadel of the Château d'Oleron on the island of Oleron.

The fort was positioned so that the crossfire from the castle and the citadel would control the Channel of Maumusson and prevent access to the roads of Rochefort from the south. Fort Lavoie was a battlefield near the end of World War II, when bombings severely damaged the fort, making it necessary to rebuild it afterwards.

Where did saucer flying machines come from?🤔

Few people think about it, but the image of "saucers" in modern life and comes from the distant past.

On bas-reliefs, drawings and various writings, ancient peoples mentioned "gods" and saucer-like vehicles. These images were found in Egypt, South America, Asia and Europe.

Why are the "coincidences" in denoscriptions of flying machines the same all over the world?

Jan Meeker's Vogelevlucht 1652.

Nothing surprising - the author simply detailed and depicted Amsterdam as accurately as possible from a bird's eye view, with shadows cast by passing clouds. 131 years before the first balloon was invented.

"Unbreakable" paints of ancient Egypt

This country is a favorite among archaeologists because many of the greatest discoveries of the past have been made there. Scientists believe that the sands of the Egyptian desert hide many more mysteries than we can imagine. Many tombs have been found there, but one in particular has striking drawings. The tomb is 4,400 years old and belongs to an official named Huvi, who lived at the time the pyramids were built. According to the innoscriptions on the walls, he was the only one close to the pharaoh and an important person. But it is not his mummy that is valuable, but the paintings that surround the sarcophagus. They show peasants working in the fields, ships sailing on the Nile and various ornaments. It is a mystery to scientists how the Egyptians were able to create colors that do not fade for several thousand years.

An ancient city found in Peru at more than 4'000m altitude

The officials' verdict is perfect - this structure was built for defence. There is no water source on the cliff and it is useless to grow anything - it is not much of a shelter. A single narrow path leads to the fortress over a precipice and out onto the flat ground in front of the structure itself. Shooting enemies on a road with nowhere to run? Nah, the experts said that a separate structure on the edge of the town with an opening in the centre was made for defence. It makes sense: we wait for the enemy to walk along the path, enter the town, inflict damage and come within firing distance to the very edge of the town, that's when he'll be shot... Well, scientists are not tacticians, they are allowed to make such claims.

A giant belted statue 150 metres high and 20,000 years old

The figure, named Dame of Mali, is located on the border between Guinea and Mali. It is carved into a granite mountain and lies 1.5 km above the ground - or rather, above an abyss.

What kind of Paleolithic civilization is this? Possessing the technology to create statues of such gigantic proportions?

Before Our Time📜

This mermaid was a gift to the British Museum by Queen Victoria's grandson, and is said to have been caught in Japan in the 18th century.

The peculiar structure of this creature is surprising - literally two halves: the upper part of the body resembles a monkey, and the lower part resembles a fish tail. You involuntarily think of the old tales of underwater cities and their inhabitants, which may very well be real, judging by such findings.

The megalithic complex of fused granite called Bektua-Ata defies explanation

Experts claim that fused granite cannot exist in nature, otherwise it collapses into sand when heated strongly, but the rule does not seem to apply to this site.

Before Our Time📜

Sometimes, the processing of stones by our ancestors baffles modern science. Tambochai, Sigiriya are famous not only for their megaliths, but also for the unusual processing of them. Clear traces of stone melting, traces of rock flowing down do not fit the story of primitive peoples very well.

There is an interesting example at Machu Picchu, where both polygonal masonry and matching blocks, and a flat wall with no traces of machining, meet in one section.

Saturn's rings were discovered back in Mayan times

Mayan artefacts with alien 'teachers' and flying vehicles are no longer surprising.

Pictured: image of planetary rings. What is interesting, the rings of Saturn were discovered by Galileo in 1610. The Mayans beat him to it.

About the "caves of heaven"

Mustang Kingdom is an isolated area of the Himalayan mountains. Some of the grottoes near the Tibetan plateau are made to the height of a ten-storey house. That the caves were used by humans is confirmed by the finds inside: household objects, hearths, cult objects and burials.

How did people climb to such heights? There had been no mountaineering equipment.
