If we turn to the official history, we find out interesting information, how it was all done by hand, cut, polished, etc.
But the columns 30 meters high cannot be made manually, and this is not a guess, but a fact. Without high technology, it is impossible to cut out a granite monolith, and then create a 30-meter and 100-ton cylinder from it, to be more precise, even now it is impossible.
How were such columns supposed to be created? Something had to hold them, rotate them at great speed and process them, in other words, this is some kind of machine of incredible dimensions, or unknown technologies.
Strange "patches" on the columns of St. Isaac's Cathedral are well known. So here is one of the assumptions that these are traces of retention in the machine. Just imagine what kind of machines they were?
You can move a little away from St. Isaac's Cathedral. Columns in the temples of India, which are generally difficult to explain in any way, Pompey's Column, Alexander's and many others, which by modern standards are impossible to create.

Does everyone know how they create columns now? And the fact is that they are collected piece by piece, since the technology does not allow it in any other way. That is, a monolithic column, for example, 30 meters high, now no one can make, neither by manual labor, nor by machines and equipment.
Why could such columns be made? In fact, there are several versions, but only one has many confirmations, namely, such columns around the world gave energy wirelessly. This topic is also quite large and in one of the next articles I will give facts regarding this version.
As for the technologies with which such columns could be made, it is difficult to give a definite answer. These were either huge machines, superior to modern ones by 5 times, or some unknown technique or technology.
By the way, another interesting fact is that all columns are the same in all factors, from weight to structure. Think about it, is it possible to create identical columns by hand? This is if you forget that it is basically impossible to create them manually.
