Ancient Egyptians may have left behind a cryptic clue to a hidden second Sphinx,  carved directly into stone more than 3,000 years ago.

The Dream Stele, positioned between the paws of the Great Sphinx, appears to depict two sphinx figures, hinting that the legendary monument may once have had a twin.

Now, Italian researchers who, in 2025, claimed to have uncovered massive underground structures beneath the Giza Plateau believe they have identified the second guardian buried deep beneath the sands. 

Filippo Biondi revealed the discovery on Thursday while speaking on the Matt Beall Limitless podcast, explaining that lines drawn from the pyramids to the known Sphinx point to an identical mirrored location where the buried structure is believed to lie.

'We are finding precise geometrical correlation, 100 percent of correlation, in this symmetry,' he said, adding: 'We are very confident to announce this… we have a confidence about 80 percent.'

Using satellite radar technology capable of detecting subtle ground vibrations, Biondi claimed the data points to a massive structure concealed beneath a 180-foot-high mound of hardened sand, which he said is composed of solidified sand rather than natural bedrock. 

Preliminary scans show vertical shafts and passageways strikingly similar to those already found beneath the original Sphinx, with dense vertical lines believed to represent the solid walls of underground shafts rather than empty voids. 

Beyond the possible second Sphinx, Biondi believes the findings hint at something even larger, an extensive underground complex beneath the Giza Plateau itself.

'Down underneath the Giza Plateau, there is something very huge that we are measuring,' he said. 'There is an underground megastructure.'
