Experts have debated for years how ancient Egyptians built the complex structures around 2630BC, while some believe there’s more than meets the eye.
But Matthew Sibson, an ancient history and civilisations expert, may have come up with an explanation.
There is a universal agreement that there is a hill underneath the Great Pyramid, but Matthew believes this large mound of sound could be far bigger than previously thought.
“The estimations of the volume of the hill that makes the foundations of the Great Pyramid are based on topographic maps and the few physical observations made inside the pyramid but the truth is nobody knows,” Matthew said in his most recent video on YouTube channel Ancient Architects
“The most up-date-view is that under the Great Pyramid is a 20-metre high truncated pyramid shaped hill known as an inselberg.
“But I’m speculating, it was actually much larger.
“A larger hill would make the process of building the pyramid far easier.”
One piece of evidence surrounds the Queen’s Chamber – which sits far higher than the 20 metre-height of the inselberg that historian traditionally believe.
Matthew points out that the chamber is surrounded by cavities filled with sand and sand was also found in the Queen’s Chamber southern shaft, that had leaked through the masonry above.
He believes that sand may have been used to infill natural voids within the inselberg to give the structure more stability.
Matthew adds that every granite beam in the King’s chamber is cracked, it displays considerable subsidence and the whole room leans which also suggests the inselberg actually reaches higher than histroy books suggest.
He also explains how pictures featured in his previous videos show crude pyramid excavations that could be interpreted as tunnelling through natural rock rather than masonry.
“Why does it look like this?” Matthew asks. “Is it because the tunnels actually go through natural bedrock?”
Matthew also cites a “strange passage” from ancient Greek historian Herodotus that says the pyramid was built “from the top down”, as evidence of his theory.
Speaking to Daily Star Online, the historian admitted that he would need to see inside the crude tunnels firsthand, but said it is possible that the chambers and tunnels inside the Great Pyramid may have simply been excavated from the inselberg.
Of course, the Great Pyramid was a carefully planned construction and huge blocks of masonry were added inside and out.
It comes after an author claimed the Great Sphinx twin could be hiding under sand mounds on the Giza plateau.
