READ: Researchers Say Second Subterranean Network Found Beneath Giza Pyramid
A team of researchers using advanced radar scanning has reportedly discovered a second network of underground structures beneath Egypt’s Giza Plateau—this time beneath the Pyramid of Menkaure. According to lead technician Filippo Biondi of the University of Strathclyde, the new findings appear to echo the subterranean features previously identified beneath the nearby Pyramid of Khafre.

Speaking to the Daily Mail, Biondi claimed that the latest scans show with “90 percent probability” that the base of Menkaure contains pillars and voids nearly identical in form to those seen under Khafre. The implications are profound: the radar team believes these aligned formations may be part of a vast, interconnected labyrinth stretching 2,000 feet below the desert sands—effectively tying the three iconic pyramids together over a massive underground complex.
Imagery shared with the press reportedly depicts spiral formations encircling pillar-shaped voids, suggesting a sophisticated subterranean design. Biondi emphasized that these formations are not isolated but interconnected, forming what he describes as a "dense web of tunnels" converging on central chambers.
“The pyramids are only the tip of the iceberg,” Biondi stated, suggesting the visible monuments may rest atop a much older and more complex buried infrastructure.
Despite the sensational claims, many in the archaeological establishment remain sharply skeptical. Dr. Zahi Hawass, Egypt’s former minister of antiquities, dismissed the team’s earlier and current findings as completely unfounded. He argues that ground-penetrating radar cannot reach depths of 2,000 feet and insists the research lacks peer-reviewed support.
Hawass described the group’s March announcement regarding Khafre as “bulls***,” repeating his criticism following the Menkaure revelations. Without publicly vetted data, he asserts, these assertions remain speculative at best.
The same team previously theorized that Giza’s underground structures could date back over 38,000 years—far earlier than conventional Egyptology allows. Team member Armando Mei linked salt deposits and signs of water damage near the Great Pyramid to a prehistoric flood. He and his colleagues propose that a comet strike around 12,800 BCE unleashed a cataclysm that destroyed an advanced pre-Egyptian civilization.
Geologist Dr. James Kennett of UC Santa Barbara supports aspects of this theory, pointing to impact remnants found at Abu Hureyra in Syria—approximately 1,000 kilometers from Giza—as possible evidence of a massive regional flood. Meanwhile, independent scholar Andrew Collins highlights inscriptions at the Temple of Edfu that describe an ancient flood that wiped out a mysterious society known as the “Eldest Ones.” Traditional Egyptologists argue these texts are symbolic and have no direct link to the pyramids.
While the radar team plans to release full tomographic data “within months,” no physical evidence has yet been recovered to validate their claims. They are currently seeking permission to conduct core-drilling tests at Menkaure, which would be a major step toward confirming or debunking the supposed network.
Until such data emerges, the notion of a hidden, city-sized structure beneath the Giza Plateau remains the subject of heated debate—caught between provocative new technology and the deep-rooted skepticism of traditional archaeology.
