Many people know what Sacsayhuaman is, some have even been there, but at the same time, most do not see many interesting traces on these most amazing megalithic walls.
I'll start with the simplest, and in this case, these are perhaps incomprehensible traces, as if left by accident by ancient builders of this incredible object.
There are only a few such places and they are something like not large depressions, as if softening the stone, the civilization of builders accidentally touched the stone with something, leaving traces for millennia.
Move on. And now, in my opinion, one of the most interesting and inexplicable technologies is rounding corners. Apparently, this technology was not used as widely as many others, but in some structures traces of its use are found.
According to my version, the stone was also softened, after which it was rounded to remove unnecessary corners, and, accordingly, to strengthen the masonry. That is, without a corner, in that place, the masonry turns out to be one whole. But how it was done anyway, it is rather difficult to explain.

And probably the last traces, which few people know about, even from those who have visited Sacsayhuaman personally, are traces of melting and the impact of enormous temperatures on the megalithic walls.
There are several such places there, and everything indicates that this "temperature" was on the one hand. Although according to my version, these are traces of the use of some kind of powerful beam weapon.
At some points, you can see how the megaliths were partially destroyed, while in others they have already begun to mix with other megaliths, almost into a homogeneous mass.
After that, is it worth considering that someone attacked the inhabitants of Sacsayhuaman? - Unknown. Since, according to one of the versions, these walls were built as for a test site, that is, they were hiding behind them to test weapons.
How true this is and what happened in the past is difficult to answer. But the stones were certainly not melted by the Sun and not something else, since it is difficult to do this in the open air, moreover, to melt in several cases, several megaliths together at once.
By the way, one could also say about the technology of copying blocks, but in Sacsayhuaman, for me personally, this already raises doubts, since the obvious traces of the use of such technologies are difficult to notice.
But no matter how surprising to many, the technology of copying blocks of the same size, with the same angles, inclination, in general the same, really created, as if on a 3D printer and such examples can be seen in Egypt.
In general, no matter how famous Sacsayhuaman was and no matter how many people visited it, the mystery of the structure to this day remains unsolved, for which these three walls were built and, most importantly, how such huge megaliths were moved, after which they were installed as if they merged together - all these are questions, the answer to which has not yet been received.
And yes, do not assume that this is a cast. Since it was found and proved long ago that these huge megaliths were delivered to the place where the walls were built from the quarry, but how this was done is no longer possible to answer.
