Research Team Claims They Detected a Second ‘Hidden City’ under Egypt’s Giza Pyramids

This March, I reported that using advanced Synthetic Aperture Radar (SAR) technology, scientists from Italy and Scotland claim to have discovered a vast subterranean complex stretching approximately 6500 feet beneath Egypt’s Giza Plateau.

Now, these scientists claim they have located a “hidden city” or “vast underground city” discovered beneath Egypt’s Great Pyramids of Giza.

According to a team of researchers from Italy and Scotland (led by Corrado Malanga from the University of Pisa and Filippo Biondi from the University of Strathclyde) advanced radar technology has revealed what they describe as a massive subterranean network connecting the pyramids of Khafre, Khufu, and Menkaure, as well as the Great Sphinx.

“We firmly believe that the Giza structures are interconnected, reinforcing our view that the pyramids are merely the tip of the iceberg of a colossal underground infrastructural complex,” Biondi told the Mail.

The team’s research, which has yet to be peer-reviewed or published in any scientific journal, made waves back in March when they claimed to have found 2,000-foot-long vertical shafts underneath the Khafre pyramid.

Independent experts have raised questions about the findings.

A ground-penetrating radar (GPR) archaeological researcher at the University of Denver, Lawrence Conyers, told DailyMail.com that it is impossible for the technology to penetrate that deep into the ground.

He called the claims of an underground city “a huge exaggeration”, and instead explained that it is more conceivable that small structures, such as columns and rooms, existed beneath the pyramids before they were built.

Conyers added that the only way to prove the authenticity of the discoveries is would be to conduct “targeted excavations, and my opinion is that as long as the authors aren’t making things up and their basic methods are correct, everyone interested in the site should take a look at their interpretations.”

The group theorizes that these alleged structures are over 30,000 years old, whereas the iconic pyramids of the Giza Plateau were built about 4500 years ago.

The group dates the complex to 38,000 years ago, contending that an advanced civilization was wiped out about 12,800 BCE by a comet-triggered deluge—a timeline mainstream Egyptology rejects.

Supporters of the comet hypothesis, such as UCSB geologist Dr. James Kennett, note impact debris at Abu Hureyra, Syria—about 1,000 km from Giza—as possible evidence of regional flooding. Independent researcher Andrew Collins highlights Temple of Edfu inscriptions describing a primeval flood that destroyed a shadowy “Eldest Ones” culture. Egyptologists counter that these texts are symbolic and unrelated to Giza.

Biondi’s team says it will release full tomography files “within months” and is seeking permits for coring tests at Menkaure. Until then, the claims remain unverified—and the debate over what, if anything, lies beneath the Giza plateau shows no sign of subsiding.
