Legends of a hidden library beneath the Great Sphinx of Giza have circulated for more than a century.
Mystics call it the Hall of Records, a vault of ancient knowledge left by a forgotten civilization.
Some researchers connect the idea to Atlantis, while others believe it preserves lost histories from pre-dynastic Egypt.
For decades, mainstream archaeology dismissed these stories as fantasy.
Now, a wave of new technology and a team of determined researchers have reopened the debate with hard data.
The Hall of Records: A Legend That Refuses to Die
The Hall of Records story began gaining attention in the early twentieth century.
American mystic Edgar Cayce claimed that survivors of Atlantis hid a record of their science and history in three locations: Bimini in the Bahamas, the Yucatán Peninsula, and beneath the Sphinx’s paws.
Cayce predicted that the chamber under the Sphinx would be discovered in the late 1990s.
Egyptian texts add fuel to the legend.
Ancient writings describe “secret chambers” where the gods stored wisdom before a great flood destroyed their world.
Mainstream scholars interpret these passages as religious metaphor, but alternative researchers see them as hints of a physical archive.
Early Scientific Clues
In the 1990s, geophysicist Thomas Dobecki and Egyptologist Mark Lehner carried out seismic surveys around the Sphinx.
Their instruments recorded large underground cavities beneath the monument’s front paws and along its flanks.
The shapes looked too regular to dismiss as random cracks in limestone.
NASA satellite images later revealed additional subsurface anomalies around the Giza Plateau.
Despite these findings, Egyptian authorities allowed no excavation.
Officials argued that the cavities were natural fissures and that drilling risked damaging the monument.
The lack of access kept the mystery alive.
Filippo Bondi and the Khafre Project
In 2025, Italian researcher Filippo Bondi and his Khafre Project brought the latest tools to Giza.
Bondi’s team combined ground-penetrating radar (GPR) with muon tomography—a particle-tracking method that measures cosmic rays passing through rock.
Muon technology famously exposed hidden spaces inside the Great Pyramid in 2017.
By pairing these two methods, Bondi aimed to create a three-dimensional map of the bedrock beneath the Sphinx.
The results stunned even seasoned researchers.
Early scans showed clear underground voids directly beneath the monument.
The shapes appeared rectangular and symmetrical, unlike the irregular patterns of natural fissures.
Bondi emphasized that the data still require formal peer review, but the images speak for themselves.
Proof of Accuracy: The Osiris Shaft Test
Skeptics often ask whether scanning technology can produce false positives.
Bondi anticipated that challenge.
Before scanning the Sphinx, his team tested their equipment on the Osiris Shaft, a known underground complex first recorded in 1933.
The radar mapped the shaft’s interior with remarkable precision, matching every chamber and corridor that explorers documented decades ago.
This successful test showed that the same technology can reveal accurate details far below the surface.
Joe Rogan Challenges Zahi Hawass
The new data quickly entered public debate.
During a recent episode of the Joe Rogan Experience, Rogan confronted renowned Egyptologist Zahi Hawass with Bondi’s results.
Rogan argued that if the Khafre Project could map the Osiris Shaft so accurately, then the scans showing voids under the Great Pyramid and the Sphinx should also be correct.
Hawass pushed back, insisting that no “Hall of Records” exists and that any anomalies are natural cavities.
He maintained his long-held position that the Sphinx contains no hidden library.
Their exchange highlighted the divide between mainstream archaeology and alternative research.
On one side stand scientists who demand direct excavation before accepting extraordinary claims.
On the other side are researchers who view the new scans as compelling evidence that something significant lies beneath the Sphinx.
What Could Be Hidden Beneath the Sphinx?
If the anomalies prove to be chambers, the implications are enormous.
They could contain artifacts from Egypt’s Old Kingdom, sealed away for millennia.
They might hold records of a lost pre-dynastic culture that built advanced monuments long before the pharaohs.
Some speculate about links to Atlantis or a global civilization wiped out by a cataclysm at the end of the Ice Age.
Even a simple empty void would carry meaning.
It would confirm that the ancient builders shaped the Sphinx’s bedrock with more complexity than previously believed and that undiscovered passages may still wind beneath the Giza Plateau.
Next Steps and Global Interest
Bondi’s team plans another round of scans with even higher resolution.
They must secure final approval from Egypt’s Supreme Council of Antiquities before releasing their full data.
If officials grant access, the Khafre Project could publish the most detailed subsurface map of the Sphinx ever produced.
Such a map might guide future non-invasive probes or, eventually, a carefully controlled excavation.
International interest continues to grow.
Alternative researchers, independent filmmakers, and even mainstream engineers follow the project closely.
Every update from the Khafre Project sparks debate across scientific journals, podcasts, and social media.
Why This Matters for the Hall of Records
The search for the Hall of Records is more than a hunt for treasure.
It challenges our understanding of human history.
If a hidden chamber contains records or artifacts older than known Egyptian civilization, historians will need to rewrite timelines of architecture, technology, and culture.
Even if the voids hold nothing but empty limestone, the discovery will still prove that advanced scanning can reveal secrets beneath one of the world’s most iconic monuments.
