In the ancient city of Abydos, which according to official history was founded more than 6,000 years ago, there is the Temple of Osiris, which, even by modern construction standards, is considered very difficult to implement, if at all real.
How old the temple itself is, we do not know, but if you believe the official history, it is at least 6,000 years old. Although it is believed that this temple is one of the most ancient structures in Egypt.
But despite his age, the builders' technologies, apparently, were no worse than ours, and most likely much better. It's worth starting with the large granite blocks from which the entire temple is built.
The multi-toned granite blocks are not only perfectly processed, created in size, but also fitted so perfectly that not even a blade will pass through the gap between them.
All this was discovered only in the XX century, at least according to official information, then the structure was excavated. In addition, as you can see, from time to time, water arrives there.
In general, there is a lot of amazing things in Osirion, these are the stairs that are visible in old photographs, but no one knows where they lead. And also, it is known about more than 10 niches, quite large in size, which, again, no one has studied.
Promotional video:
Osirion was built at a depth of 15 meters below ground level, which raises questions about this location of the building, by ancient builders. But we know neither the purpose of the structure, nor its secrets, in the form of strange stairs, which are flooded most of the time. Therefore, one can only draw some conclusions by looking at all the same granite blocks.
But much cannot be said about blocks. Of course, they are amazing and hardly created by primitive labor, especially with this level of processing and installation, without the smallest gap. However, the building itself also has many secrets.
First, as I said, is depth. Why were they built at such a depth, one can only guess, and after all there are niches and even stairs that should lead somewhere even lower, but where?
It is also worth noting the pipe that connects to the complex and, accordingly, must let water through. But why water was needed there is difficult to answer.
In general, Osirion still keeps many secrets, which it is not known whether it will ever be possible to unravel. Now we can only note some high technologies in the past, for the creation and installation of such granite blocks.
