Polygonal masonry
Many may object, because it was made in the next hundreds of years, and even nowadays it is sometimes still used. But don't jump to conclusions, I'm not talking about simple polygonal masonry.
Who cares, this is what polygonal masonry looks like for the last 200 years. Filmed by me in the Brest Fortress.
However, there is a more complex and mysterious masonry. It is found only in 2 places on Earth - in Peru and Turkey. In Peru, you can find it in many places, but in Turkey only in Aladsha-Huyuk. It looks like this.

No one has yet been able to determine how the masonry of such an image was created. This is despite numerous studies by its scientists and independent researchers. There are only a lot of assumptions, from pouring to stone softening technology.
Apart from Peru, such masonry is found in one more place in Turkey.
I don't know how this can be explained, but the fact remains.
All other similarities of polygonal masonry most likely came from the ones I described above, so they do not raise so many questions.
How and who managed in ancient times to achieve such an ideal curvilinear conjugation of blocks remains a mystery.
Amazing stone processing without traces of primitive tools
I am not denying here that the ancient people could not handle stone well, but there is a small exception. In some places, this processing occurs on a huge scale and with incredible precision.
Where did so many talented workers come from? But there are artifacts that are made like a blueprint, although made of granite, for example.
I forgot to add the most important thing at this point. Most artifacts with this processing show no traces of primitive tools. How can you process such a hard rock mass without leaving even tool marks?
Although, there are traces of tools, only no primitive tools could leave them.
But if the processing was not done with simple tools, like a chisel or copper tools with an abrasive, then how?
At the moment, this technology can be considered lost.
