NEW: Massive Underground Structures Beneath Khafre Pyramid
A recent radar survey has revealed a vast subterranean complex beneath the Pyramids of Giza
Using Synthetic Aperture Radar (SAR) tomography, a team of researchers—including Corrado Malanga (University of Pisa) and Filippo Biondi (University of Strathclyde)—scanned the Khafre Pyramid and detected significant underground anomalies.
Findings announced in a scientific paper and a press release on March 15, 2025, suggest a complex network of structures extending beneath the Giza Plateau.
Key Discoveries
The SAR scans revealed the following features beneath the Khafre Pyramid:
Eight large cylindrical structures descending 648 meters below the surface.
Five stacked, multi-level chamber structures near the pyramid’s base.
Geometric passageways connecting the chambers.
A system of tunnels extending approximately two kilometers, possibly linking structures beneath all three major pyramids.
Two massive cube-shaped underground chambers, each 80 meters per side, located at the base of the cylindrical structures.
These findings indicate that the construction of the Giza pyramids involved more underground complexity than previously documented.
For perspective, the Great Pyramid of Khafre is 146.6 meters (481 feet) tall while the cylindrical structures SAR scans are suggesting are 648 meters (2126 feet) tall.
Scientific and Public Response
The discoveries have generated widespread discussion online, with some users on X (formerly Twitter) calling it one of the most significant archaeological finds in recent history. The findings have also sparked renewed interest in alternative interpretations of the pyramids’ function.
However, mainstream Egyptology continues to focus on the pyramids as tombs built using labor-intensive methods. Dr. Sara Schrader from the University of Leiden has studied human remains found near pyramid sites, concluding that some of those buried there were laborers, challenging the idea that these sites were exclusively for royal burials.
Potential Future Excavation
The Khafre Project team has expressed interest in further exploration of the site. However, Egypt’s government has historically been cautious about approving excavations that might challenge its official stance on the pyramids' historical purpose. At this time, no official excavation has been announced.
For now, the details of these newly discovered underground structures remain under investigation. Whether further studies will be conducted or excavation will be permitted is yet to be determined.
