Italian researchers announced they have uncovered a second ancient city deep underground near the Giza pyramids, fueling their theory that a vast hidden city lies beneath the desert sands.
Based on their controversial findings, a network of shafts and chambers connects the pyramids underground, potentially forming what they describe as a massive subterranean complex more than 2,000 feet below the surface.
The team first reported similar underground formations beneath the Khafre pyramid in March. Their latest scans, taken months later, indicate comparable structures beneath the nearby Pyramid of Menkaure.
Radar specialist Filippo Biondi from the University of Strathclyde in Scotland said their data shows a 90% probability that Menkaure features the same pillar-like architecture found beneath Khafre. “The measurements reveal pillar-like structures with consistent characteristics,” he told the Daily Mail.
He added that although Menkaure is smaller, it likely contains fewer but similar formations. Those beneath Khafre were estimated to stretch over 2,000 feet, with spiral features wrapping around eight distinct pillars.
The team believes these pillars are part of a much larger network of underground tunnels, suggesting the visible pyramids may only be surface-level elements of a deeper, interconnected design. “Discoveries like these under Menkaure challenge us to rethink our understanding of ancient Egyptian history and humanity’s past,” Biondi said.
The research has not been peer-reviewed or published in a scientific journal. Still, it has drawn widespread attention. Podcast host Joe Rogan called the theory “fascinating,” while mainstream archaeologists have dismissed the claims as speculative.

Dr. Zahi Hawass, Egypt’s former head of antiquities, strongly criticized the findings, calling them false. He said ground-penetrating radar cannot reach the depths the team claims, and emphasized that the technology used does not provide sufficient proof to support their conclusions.
Despite the criticism, Biondi and his team continue to investigate. They suggest the purpose of the underground structures may relate to elemental forces such as air, water, fire, and earth, though they are still gathering data.
The researchers also propose that the site may date back 38,000 years, significantly older than the pyramids’ accepted age of approximately 4,500 years.

Their timeline comes from a broader theory that a prehistoric civilization was destroyed by a global cataclysm—possibly a comet strike—about 12,800 years ago. They suggest some survivors passed their knowledge on to later cultures, including ancient Egyptians.
Supporting this theory, geologist Dr. James Kennett of the University of California, Santa Barbara, pointed to evidence of a sudden population drop in North America around the same time. He said impact debris found in Syria could indicate a regional event that caused widespread flooding in parts of the Middle East, including Egypt.
Author Andrew Collins added a mythological dimension, citing texts from the Temple of Edfu that reference a great flood and the destruction of a mysterious people known as the “Eldest Ones.”
He believes the serpent described in the inscriptions may symbolize a comet and that the texts mention sacred items hidden in a subterranean chamber, possibly referencing the same hidden city beneath the Giza pyramid complex.
Mainstream scholars disagree, viewing the Edfu inscriptions as symbolic rather than historical. They argue there is no direct link between the myths and Giza, and no evidence supports the existence of an ancient lost civilization under the plateau.
