Italian researchers have sparked a major debate in the field of archaeology by claiming they have identified a second Great Sphinx buried deep beneath the Giza Plateau. Lead researcher Filippo Biondi announced on the Matt Beall Limitless podcast that his team is “80 percent confident” in the discovery, which was made using a combination of satellite radar technology and a revolutionary geometric analysis of the ancient site.
The theory is rooted in the “Dream Stele,” a 3,000-year-old monument positioned between the paws of the original Sphinx. While historians have traditionally viewed the stele’s depiction of two sphinxes as purely symbolic, Biondi’s team argues it serves as a literal map. By tracing precise “mirrored” lines from the centers of the Great Pyramid and the Pyramid of Khafre, the researchers identified a location that perfectly mirrors the existing Sphinx—a spot currently hidden under a 108-foot-high mound of solidified sand.
Using advanced satellite radar capable of detecting ground vibrations and subsurface density, the team’s scans revealed startling features beneath the sand that appear to mirror the original monument. Biondi reported finding vertical shafts and horizontal passageways that are identical in layout to those found beneath the known Sphinx, suggesting a “100 percent geometrical correlation” in the symmetry of the two sites. Crucially, the scans indicate that the mound covering the site is composed of “solidified sand” rather than natural bedrock, implying the structure was covered over millennia.
The concept of a “Twin Sphinx” has circulated for over a decade, notably championed by Egyptologist Bassam El Shammaa, though it has been frequently dismissed by high-profile authorities like former Minister of Antiquities Zahi Hawass. Biondi counters this skepticism by noting that the second structure is likely buried much deeper or encased within the artificial mound, requiring modern technology to bypass the debris. The team has already identified several potential entrances, including one large shaft blocked by rubble that they believe can be easily cleared to provide safe access to the chambers below.
The research team is now moving into the physical phase of the project, having drafted a formal proposal for the Egyptian authorities to conduct in situ geological studies. If granted permission, the team plans to investigate the mound and the specific shafts identified between the first Sphinx and the Khafre pyramid. While the digital evidence is compelling, Biondi emphasizes that physical confirmation remains the final hurdle to proving that one of the world’s most famous monuments has a long-lost twin.
