Giza's largest pyramid, dubbed the ancient world natural wonder, remains a great mystery to the world.
The three large pyramids on the Giza plateau are lined up with three stars that make up the constellation of Orion's Belts.
Scientists discovered that the Giza pyramid in Egypt was deflected to one side, with the western side longer than the eastern flank.
To make it easier to imagine, the One World Trade Center building, 500mt tall in downtown Manhattan (USA), only has a construction cost of about 4 billion USD.
Archaeologists in Egypt unearthed two buildings dating to about 4,500 years old that are most likely related to the construction of the pyramids at Giza.
So far, there has not been an official, complete, accurate answer to the mysteries of the Pyramid.
