Incredible new discovery underneath Egyptian Sphinx fuels theory of lost underground city

The same team that brought new ideas to light about the massive structures beneath the Pyramid of Khafre earlier this year now say they have identified a colossal vertical shaft leading to two chambers below the Sphinx in Egypt.

These findings were shared for the first time at the recent Cosmic Summit in North Carolina, an event where it is commonplace to put forward alternative historical theories.

Scans reveal a huge shaft, which is surrounded by a spiral-like staircase that descends from the centre of the Sphinx's base and down into two square structures, one at 2,000 feet and another 4,000 feet underground.

Radar expert from the University of Strathclyde in Scotland and co-author of the research Filippo Biondi, told DailyMail.com: "These findings strongly support the hypothesis that then Giza Plateau conceals a vast subterranean complex, potentially indicative of an extensive underground city."

However, many mainstream archaeologists have dismissed their research, on both the Pyramid of Khafre and now their new findings on the Sphinx, calling the work unscientific and speculative.

This hasn't stopped the research team, who insist that their latest scans point to something extraordinary.

"The discovery proves that the Giza Plateau was engineered long before the dynastic era, possible around 36,400 BCE, as my research suggests," Egyptologist Armando Mei, co-author of the research notes.

He adds that similar underground features have now been detected beneath all three major pyramids, suggesting a unified architectural blueprint.

The research has the potential to rewrite history, overriding the common belief that the pyramids and Sphinx were built roughly 4,500 years ago.

Their previous research came into the public eye in March, utilising cutting-edge SAR Doppler Tomography in order to create 3D maps which highlighted four massive shafts and chambers underneath the Pyramid of Khafre.

Despite these bold claims, their research is yet to be published in a scientific journal for the review of independent experts. An official study is planned to be published in 2026.

These underground findings could point to a whole lost city beneath the surface, and the researches claim that the pyramids are the only surviving evidence of this supposed mega-city.

They theorise that it was destroyed 12,000 years ago by a 'divine flood' triggered by an asteroid impact.

Such a discovery could potentially even shed some light on the mysterious Hall of Records, a mythical chamber said to lie beneath the pyramids containing documents of ancient wisdom.

However, no such room has so far been proven to exist, and for now remains a legend.

To further prove their research, the team now hopes to gain permission from Egyptian authorities to excavate beneath the Giza Plateau, which could shed light on a whole new side of previously-obscured human history.
