====== The Pyramids - construction ======

Construction engineers and archaeologists have not been able to agree on ways in which the [[https://en.wikipedia.org/wiki/Great_Pyramid_of_Giza|Great Pyramids of Giza]] (and others) might have been constructed - at around 2580–2560 BC.

>The logistics involved in the construction of this pyramid are staggering when one considers that the ancient Egyptians had no pulleys, no wheels, and no iron tools.\\ 
>The dimensions of the pyramid are extremely accurate and the site was leveled within a fraction of an inch over the entire base. This is comparable to the accuracy possible with modern construction methods and laser leveling."   \\ \\ Source : [[https://web.archive.org/web/20070608101037/http://www.pubs.asce.org/ceonline/0699feat.html|Civil Engineers Magazine]] 1999, (archived)

Also, some of the limestone and granite blocks weigh more than 20 tons, and there is no agreement about how they may have been cut and moved.
