Fresh radar work on the Giza Plateau is reviving one of archaeology’s most persistent questions: what, if anything, lies hidden beneath the Great Sphinx. New subsurface scans point to a void beneath the monument’s forepaws, a tantalizing anomaly that sits at the crossroads of hard geophysics, Egyptological caution and a century of speculation about secret chambers.
Rather than confirming legends outright, the latest data sharpen the stakes of the debate, suggesting a structured cavity that demands explanation while stopping short of revealing its contents. I will walk through what the technology is actually showing, how it connects to long running theories about a buried archive and why the Sphinx has become the focal point of a much broader reexamination of what lies under the Giza Plateau.
New radar eyes on the Giza Plateau
The story of a possible chamber beneath the Sphinx’s paws begins with a wider technological push under the entire Giza Plateau. Earlier this year, an interdisciplinary team working with synthetic aperture radar, or SAR, began mapping what lies below the surface around the Great Pyramids, using techniques sensitive enough to pick out voids and structural contrasts deep underground. Their work, described as part of a project titled Below The Giza Pyramid Plateau, is designed to reveal cavities and buried architecture that traditional excavation would struggle to reach without major risk.
In March, that same interdisciplinary team reported radar signatures consistent with voids and linear features deep below the Great Pyramids, suggesting a more complex subsurface landscape than the visible monuments alone imply. I see the Sphinx work as a natural extension of that effort, applying the same SAR toolkit to the limestone outcrop and surrounding bedrock that form the lion body and human head. When those scans highlight a discrete anomaly beneath the forepaws, they are not an isolated curiosity but part of a broader pattern of newly detected cavities under Giza that now require careful, methodical interpretation.
How a void beneath the paws fits the Sphinx’s known anatomy
To understand why a cavity under the paws matters, it helps to recall how the Great Sphinx itself is built. The core of the monument is carved directly from the Giza bedrock, with the lion body and paws emerging from a single limestone ridge, then finished with added masonry in places where the stone was weak or eroded. Any subsurface void in that zone, especially one that appears geometrically defined rather than a random fissure, raises questions about whether it is a natural feature in the limestone or a deliberately cut space later sealed beneath the sculpture.
Radar anomalies alone do not prove the existence of a chamber, let alone its purpose, but the location is striking. A void centered beneath the forepaws would sit at the symbolic threshold of the monument, between the lion body and the plateau, in a place that ancient builders could have accessed while the Sphinx was being carved. The new SAR signatures, read alongside earlier geophysical hints of tunnels and cavities around the statue, suggest that the Sphinx’s anatomy may include hidden architectural elements that were never meant to be visible from the surface.
The long shadow of the Hall of Records myth
Any mention of a hidden space under the Sphinx immediately collides with a powerful modern myth: the so called Hall of Records. In the 1930s, the American clairvoyant Edgar Cayce claimed that refugees from Atlantis had built a secret archive at Giza to preserve their knowledge, a repository he called the Hall of Records and linked explicitly to the Sphinx. Those assertions, rooted in spiritual readings rather than archaeology, have fueled decades of speculation that a vast library of ancient wisdom lies sealed beneath the monument’s paws.
Professional Egyptologists have repeatedly pointed out that there is no textual or material evidence from pharaonic times describing such a Hall of Records, and that Cayce’s narrative reflects early twentieth century fascination with lost continents more than Old Kingdom reality. Yet the idea has proven remarkably durable, resurfacing whenever new technology hints at voids or tunnels under the plateau. The latest radar anomaly will inevitably be folded into that story, even though the data themselves say nothing about Atlantean refugees or a global cataclysm, only that a cavity of some kind may exist in a geologically and symbolically charged spot.
Esoteric funding and the search for a buried archive
The persistence of the Hall of Records myth has not been purely cultural; it has also shaped where money and attention flow. The Association for Research and Enlightenment, founded to promote Cayce’s work, has periodically backed investigations at the Giza Plateau in hopes of finding physical confirmation of his readings about the Hall of Records. Those efforts have included geophysical surveys and collaborations with Egyptian authorities, always framed by the expectation that a hidden archive might one day be revealed.
From my perspective, the new radar work under the Sphinx sits at an uneasy intersection of that esoteric legacy and mainstream archaeological practice. On one hand, the tools now being deployed, including SAR and other noninvasive methods, are standard in serious fieldwork and can map subsurface features with impressive resolution. On the other, some of the funding and public enthusiasm for probing beneath the paws is still animated by Cayce’s vision of a buried library, even though previous campaigns inspired by the Hall of Records have yielded no such archive. The challenge for researchers is to leverage the interest and resources generated by that mythology without letting it dictate the interpretation of the data.
Earlier hints of tunnels and cavities around the Sphinx
The idea that the Sphinx might conceal internal spaces is not new, and the latest scans build on a patchwork of earlier observations. In the early 1990s, for example, Egyptian officials and visiting researchers debated reports of anomalies detected near the monument, including suggestions of tunnels and small voids. A widely discussed account from that period, later recounted in a Dec thread that was Edited, described how ground penetrating radar and seismic tests hinted at subsurface features, though access and interpretation remained tightly controlled.
Those earlier efforts did not produce a consensus about large, architecturally finished chambers, but they did establish that the bedrock around the Sphinx is not a uniform block. Natural fissures, ancient quarry cuts and later restoration tunnels all contribute to a complex subsurface environment. The new radar anomaly beneath the paws therefore arrives in a context where smaller cavities and passages are already known or suspected, but where the existence of a significant, intentionally hidden room remains unproven. That history makes it all the more important to distinguish between a void that could be a structural flaw or maintenance shaft and one that truly represents a designed chamber.
Separating purported cavities from proven structures
Beyond the Sphinx itself, the wider Giza complex has long been associated with stories of secret tunnels and rooms, many of them exaggerated or misinterpreted. Catalogs of Purported Cavaties under the Great Sphinx and nearby monuments often repeat claims about The Hall of Records as if they were established fact, even though systematic surveys have so far found little or no evidence of a vast underground library. The Great Sphinx, carved around circa 2500 BCE, does sit amid a network of tombs, causeways and quarries, but that documented infrastructure is very different from the imagined labyrinth of esoteric lore.
When I look at the new radar signatures, I see them as another data point in a long process of winnowing rumor from reality. A void beneath the paws could eventually join the list of confirmed features, like known restoration tunnels and burial shafts, or it could turn out to be a minor irregularity that gained outsized attention because of its location. The key is that previous investigations into The Hall of Records and other alleged chambers have repeatedly yielded little or no results, which should temper expectations even as the technology improves. The burden of proof remains on those who claim a major new structure, not on skeptics who ask whether a given anomaly might have a more mundane explanation.
Cosmic Summit, Khafre Research Project and the politics of revelation
The institutional landscape around these discoveries is also shifting. A recent announcement highlighted a Collaboration Between the Cosmic Summit and the Khafre Research Project, built around SAR and related technologies, to unveil new findings beneath the pyramids. That partnership, framed as global news, underscores how subsurface research at Giza now sits at the intersection of academic work, conference spectacle and media savvy branding, with each stakeholder eager to shape the narrative of what has been found.
In that environment, a potential chamber under the Sphinx’s paws becomes not just a scientific puzzle but a communications challenge. Organizers of high profile events want headline ready revelations, while the Khafre Research Project and other technical teams must balance that appetite with the slow, incremental nature of geophysical interpretation. I see the decision to route some announcements through venues like the Cosmic Summit as a sign that discoveries under Giza are being packaged for a global audience from the outset, which can amplify both legitimate excitement and unwarranted hype around features that are still only partially understood.
What the new anomaly can and cannot tell us
Given that context, it is crucial to be clear about what a radar anomaly beneath the Sphinx’s paws actually represents. SAR and related methods detect contrasts in material properties, such as differences in density or moisture, that can indicate a void or change in rock type. When those contrasts form a coherent shape, researchers infer the presence of a cavity, but they cannot see inside it or determine its age without corroborating evidence. The current data, as described in the broader Below The Giza Pyramid Plateau work, point to voids deep below the Great Pyramids and now a discrete feature under the Sphinx, but they stop short of revealing whether those spaces are natural, pharaonic or later intrusions.
From my vantage point, the most responsible reading is that the anomaly marks a target for further study rather than a discovery of a finished chamber in the full architectural sense. Drilling, endoscopic cameras or more refined noninvasive scans could eventually clarify its geometry and contents, but each of those steps carries technical, political and conservation risks. Until such follow up work is done and its results published, any claim that the void is definitively a room, a tomb or the Hall of Records itself remains unverified based on available sources. The data justify curiosity and careful planning, not premature declarations.
Why the Sphinx still matters for understanding Giza
Even if the void beneath the paws turns out to be modest in scale, the focus on the Sphinx is revealing in its own right. The monument occupies a liminal position between the pyramids and the Nile Valley, aligned with the pyramid of Khafre yet carved from the living rock rather than built stone by stone. That hybrid status makes it a natural focal point for questions about how the ancient builders conceived of the plateau’s sacred landscape, and whether they embedded symbolic or functional spaces beneath key nodes like the Sphinx’s forepaws.
The new radar work, framed by projects like Below The Giza Pyramid Plateau and the Khafre Research Project, suggests that the subsurface architecture of Giza is richer than the visible monuments alone indicate. Whether the anomaly under the paws proves to be a small maintenance cavity or something more elaborate, it is part of a growing realization that the plateau’s story extends downward as well as outward. For now, the hidden space remains a shadow on a radar plot, a reminder that even the most photographed statue on Earth may still be keeping secrets in the rock beneath its feet.
