The idea is the kind that makes people lean in—because it sounds both daring and oddly specific. Misryoum newsroom reported that an Italian researcher is claiming there’s a hidden, sphinx-like structure buried beneath the Giza Plateau.
Filippo Biondi says his team may have identified a “second Sphinx” under the Great Sphinx area. According to Misryoum reporting, the discovery came after analyzing alignments between the pyramids and the existing Sphinx, which he believes points to an underground parallel structure. It’s not just geometric guesswork, he adds—ancient clues are part of the package too.
The team also cited the Dream Stele, arguing it references two feline figures and could be evidence of a second Sphinx. That stele has been discussed for years in different contexts, and Biondi’s interpretation is the latest twist. Misryoum editorial desk noted that this kind of reading—connecting text to buried features—is where the debate starts, because you’re sort of trying to make two different timelines “click” together.
Using satellite imaging, Biondi claimed researchers detected a structure roughly 108 feet tall. He described vertical shafts and horizontal passages beneath the site, and said those features suggest a larger “underground megastructure” mirroring the original. In a quiet room, even just the faint whir of a computer fan feels louder when you’re looking for something that might not be there—except, in this case, the claim is that it is.
Misryoum analysis indicates the “second Sphinx” idea isn’t entirely new. Egyptologist Bassam El Shammaa has previously pointed to mythology and historical interpretations, suggesting more could lie beneath the surface. Actually, “previously” is doing a lot of work here—because the new part isn’t the question, it’s the attempt to answer it with a specific underground shape.
Still, the big eyebrow-raise is whether the evidence holds up beyond interpretation. Alignments can be persuasive, sure, and satellite hints sound promising, but shafts and passages are exactly the sort of things that can be over-read—or under-explained—depending on how the data is treated. And if you think about it, the phrase “megastructure” alone sets a high bar. For now, Biondi’s claim adds another layer to Giza’s ongoing mystery, even as the discussion underneath the discussion stays unfinished.
