Researchers have identified a possible second Sphinx buried deep beneath the sands, according to Italian researcher Filippo Biondi. Satellite radar technology detected a massive structure concealed beneath a 180-foot-high mound of hardened sand, Biondi said, with preliminary scans showing vertical shafts and passageways strikingly similar to those found beneath the original Sphinx. The mound is composed of solidified sand rather than natural bedrock, Biondi added, suggesting artificial origins. According to Daily Mail - Home, Filippo Biondi described having about 80 percent confidence in the announcement, though the exact nature and purpose of the underground structure remain unclear.
Geometric alignments from the pyramids to the known Sphinx point to an identical mirrored location where a buried structure is believed to lie, Biondi claimed. According to Daily Mail - Home, Filippo Biondi described finding precise geometrical correlation in this symmetry. He also asserted there is an extensive underground complex beneath the Giza Plateau, though definitive archaeological evidence confirming the existence of a second Sphinx has not been established. These claims build on interpretations of the Dream Stele, positioned between the paws of the Great Sphinx, which appears to depict two sphinx figures, according to major media reports.
We are finding precise geometrical correlation, 100 percent of correlation, in this symmetry.
The discovery was announced by Italian researchers in 2025, who claimed to have uncovered massive underground structures beneath the Giza Plateau, as reported by major media. Filippo Biondi revealed the findings on Thursday while speaking on the Matt Beall Limitless podcast, according to major media. The research team includes independent figures, but it is unclear what Egyptian authorities or mainstream archaeologists currently say about these specific claims, beyond past dismissals.
New footage revealed dozens of deep shafts surrounding a mysterious mound at Giza, according to major media reports. The video documented more than 100 shafts clustered around the site in the northwest corner of the plateau, major media said. Trevor Grassi of the Archaeological Rescue Foundation released the footage, major media reported. According to Daily Mail - Science & Tech, Trevor Grassi described endless shafts all over the place going straight down, all blocked with sand, though how they were originally used and whether they connect to the alleged structure is unknown.
We are very confident to announce this… we have a confidence about 80 percent.
Many shafts extend deep underground but are filled primarily with sand, major media reported. The shafts are carved into limestone, with some about three feet across and others roughly eight feet wide, according to major media. Many shafts appear to extend more than 100 feet underground, Trevor Grassi said, as reported by major media. According to Daily Mail - Science & Tech, Filippo Biondi described something very huge underneath the Giza Plateau, calling it an underground mega structure, but further investigations or excavations to verify these findings have not been detailed.
Skepticism from mainstream archaeology has emerged, with Zahi Hawass, Egypt’s former minister of antiquities, dismissing similar claims in the past, according to major media. Hawass has not commented specifically on the latest announcements, leaving the validity of the findings in question. The lack of official endorsement highlights the ongoing debate between independent researchers and established archaeological authorities.
Down underneath the Giza Plateau, there is something very huge that we are measuring. There is an underground mega structure.
Endless shafts all over the place going straight down, all blocked with sand.
We are very confident to announce this… we have a confidence of about 80 percent.
