The complexity of the construction of the pyramid and implicitly the genius visionary architect Hemienu consisted in the fact that as the pyramid is high: descending passage (in the opposite direction, in an outward direction), passage ascendant horizontal passage and the Queen, Great Gallery, the King, The Obdurate cameras, the let-down, as well as all the other rooms and passages still unearthed.
The outer shell of the Great Pyramid, the inner passages and chambers were made in a natural size in the ground processing workshop on segments of five rows. When the segment no. 1 was made (on the current position of the pyramid) the 5th row was dismantled (previously the stone blocks were numbered) and reassembled in the ground processing workshop near the pyramid, becoming the no. 1 of the second segment of construction of the pyramid.

There is a lot of work, ingenuity, determination, and
The REST IS HISTORY.
