Claims of Vast Underground City Beneath Giza Pyramids Stir Debate
A purported groundbreaking discovery beneath the Egyptian pyramids has ignited global interest and controversy.
Researchers from Italy and Scotland assert they have identified a substantial subterranean complex stretching over 6,500 feet directly beneath the Pyramids of Giza. This alleged “underground city” would be ten times larger than the pyramids themselves, according to the researchers’ claims.
Radar Technology Used in Controversial Study
This sensational assertion, which has already faced skepticism from numerous experts, stems from a study utilizing radar pulses. This technology, similar to sonar used for ocean mapping, was employed to generate high-resolution images of the subsurface beneath the ancient structures.
The research paper, which is yet to undergo peer review by independent specialists, reportedly identified eight vertical, cylinder-shaped formations extending more than 2,100 feet below the pyramid base. Furthermore, the study suggests the existence of additional, unidentified structures situated 4,000 feet deeper.
A press release accompanying the findings heralded them as “groundbreaking,” suggesting they could potentially rewrite the established history of ancient Egypt. However, these conclusions have been met with considerable doubt from independent experts in the field.

Expert Skepticism Regarding Depth of Penetration
Professor Lawrence Conyers, a radar expert specializing in archaeology at the University of Denver, expressed significant reservations. Speaking to DailyMail.com, Professor Conyers stated that current technology is unlikely to penetrate the ground to such depths, deeming the notion of a vast underground city “a considerable exaggeration.”
Professor Conyers conceded that smaller formations, such as shafts or chambers, may exist beneath the pyramids, possibly predating their construction. He suggested the site held particular significance for ancient populations.
He drew parallels to ancient Mesoamerican cultures, noting, “the Mayans and other people in ancient Mesoamerica often built pyramids on top of the entrances of caves or caverns that had ceremonial meaning to them.”
Scientists employed advanced radar technology to investigate below the Giza pyramids, discovering evidence of a possible “vast underground city.”

Study Details and Peer Review Process
The research is attributed to Corrado Malanga of Italy’s University of Pisa and Filippo Biondi from the University of Strathclyde in Scotland. The findings were initially presented at an in-person briefing in Italy this week. Crucially, the study has not yet been published in a peer-reviewed scientific journal, a process necessary for independent expert evaluation and validation.
Despite the prevalent skepticism, Professor Conyers acknowledged that “targeted excavations” would be the definitive method to verify or refute the claimed discoveries.
“My take is that as long as authors are not making things up and that their basic methods are correct, their interpretations should be given a look by all who care about the site,” he stated.
“We can quibble about interpretations, and that is called science. But the basic methods need to be solid,” Professor Conyers added, emphasizing the importance of methodological rigor.
He also conveyed to DailyMail.com that he could not ascertain if the technology employed had accurately detected subterranean structures beneath the pyramid.
“They are using all kinds of fancy proprietary data analysis software,” Professor Conyers noted regarding the researchers’ methodology.
Giza Pyramid Complex Context
The Giza complex comprises three principal pyramids: Khufu, Khafre, and Menkaure. These monumental structures were erected approximately 4,500 years ago on a rocky plateau on the west bank of the Nile River in northern Egypt.
Each pyramid was commissioned by a pharaoh. The Great Pyramid, dedicated to Khufu, is the northernmost and oldest, also recognized as the largest, standing at 480 feet in height with a base width of 750 feet.
The team’s study focused on the middle pyramid, built for Khafre. Menkaure’s pyramid is the southernmost and the last to be constructed within the Giza group.
Researchers’ Backgrounds
Corrado Malanga’s background includes research in ufology, and he has previously appeared on platforms discussing UFO phenomena in Italy. In contrast, Filippo Biondi specializes in radar technology.
Notably, Malanga and Biondi previously published a peer-reviewed paper in the journal Remote Sensing in October 2022. This earlier study detailed findings of hidden chambers and ramps within the Khafre pyramid, along with indications of a thermal anomaly near the base.
The research team reported discovering eight cylinder-shaped structures below the Khafre pyramid, extending over 2,100 feet underground, and identified spiral patterns on the sides.
The team also indicated a hidden chamber within the pyramid containing five identical structures with sloped roofs across five levels.
Advanced Radar Technique Utilizing Satellite Data
The recent study utilized similar radar technology, enhanced by data from an Earth-orbiting satellite.
This novel radar technique integrates satellite radar data with subtle vibrations arising from natural seismic activity. This combination is purported to construct 3D representations of subsurface features without requiring any excavation.
Nicole Ciccolo, the project spokesperson, stated, “A vast underground city has been discovered beneath the pyramids.”
“[The] groundbreaking study has redefined the boundaries of satellite data analysis and archaeological exploration,” Ciccolo added, emphasizing the perceived significance of the research.
Ciccolo shared a brief excerpt from the press briefing held on March 15, announcing that the full video recording of the event would be released on March 25.
Cylinder Structures as Access Points
The cylinder-shaped structures, referred to as “shafts” by Ciccolo, were described as arranged in two parallel rows. They are reportedly encircled by descending spiral pathways.
The shafts are reportedly linked to larger, cubic structures. Researchers suggest a hidden city could exist beneath all three Giza pyramids.
Ciccolo suggested that these cylinder structures, found under each of the three pyramids, appear to “serve as access points to this underground system.”
The research team postulates that the system involves interconnected chamber-like structures extending beneath all three pyramids.
Halls of Amenti Connection
“The existence of vast chambers beneath the Earth’s surface, comparable in size to the pyramids themselves, [shows] a remarkably strong correlation between the legendary Halls of Amenti,” Ciccolo asserted, referencing a concept from esoteric Egyptian beliefs.
“These new archaeological findings could redefine our understanding of the sacred topography of ancient Egypt, providing spatial coordinates for previously unknown and unexplored subterranean structures,” she concluded.
Public Interest and Future Research
News of the alleged discovery has rapidly spread online, generating considerable discussion across social media platforms this week.
U.S. Congresswoman Anna Paulina Luna of Florida also shared information about the reported structures on her social media profile.
The research team intends to continue their investigations throughout 2025, suggesting further analysis and potential developments are anticipated.
