The Giza Plateau’s Second Sphinx: Satellite Scans Uncover a Potential Subterranean Megastructure

On March 26, 2026 (UTC), a groundbreaking report from the Daily Mail sent shockwaves through the archaeological community, suggesting the existence of a second, hidden Sphinx on the Giza plateau. Shortly after the initial report, at 23:37 UTC, independent researcher Jay Anderson, known as @TheProjectUnity, corroborated the findings by citing data from Professor Filippo Biondi of the Khafre Pyramid Project. By the morning of March 27 (UTC), the discourse intensified as links to the professor’s comprehensive interview began circulating globally, elevating the discovery to a new level of scientific scrutiny.

Professor Biondi’s team utilized cutting-edge satellite technology, specifically Synthetic Aperture Radar (SAR) and Doppler tomography, to peer beneath the desert surface. These sophisticated methods detect minute ground vibrations and map deep-seated structures without the need for invasive excavation. The preliminary scans revealed a massive mound of solidified sand standing approximately 33 meters (108 feet) tall, which conceals a network of vertical shafts and horizontal corridors. These features, along with dense vertical lines interpreted as subterranean walls, appear to mirror the known underground complex located beneath the Great Sphinx.

The research team also conducted a rigorous geometric analysis of the site, discovering that the layout follows a precise mathematical logic. Lines drawn from the centers of the Pyramids of Khafre and Khufu to the existing Sphinx exhibit perfect symmetry, with the mirror point landing exactly where the new structure is located. Biondi noted a 100% geometric correlation and described the symmetry as "incredible," placing his confidence in the discovery at roughly 80%. Furthermore, the scans hint at a much larger reality: a vast, interconnected megastructure spanning the entire Giza plateau.

This modern scientific breakthrough finds echoes in ancient history and long-standing theories. For over a decade, Egyptologist Bassam El-Shammaa has pointed to the Dream Stele, dating back to approximately 1401 BC, which depicts two sphinxes rather than one. Some historical interpretations suggest a second monument might have been destroyed by a lightning strike or a divine curse. While former Minister of Antiquities Zahi Hawass dismissed such claims in 2017 based on previous excavations, Biondi’s team is now moving forward with a formal proposal to Egyptian authorities. They aim to conduct on-site geological surveys, clear blocked entrances, and investigate the newly identified shafts.

Although these findings remain preliminary and await physical verification, they highlight the transformative power of satellite technology in 21st-century archaeology. Features that remained buried under the shifting sands for millennia are now becoming visible on computer monitors, challenging our understanding of the ancient world. If confirmed, this discovery could rewrite the history of the Giza plateau, revealing a complex network of underground facilities that was once the stuff of legend. As scientists continue their analysis, the world watches closely to see if modern science can finally reclaim a lost piece of human heritage.
