Satellite radar study claims huge underground structures beneath Egypt’s Pyramid of Khafre
Satellite radar images reveal large underground structures extending deep beneath the Pyramid of Khafre on the Giza Plateau, according to an Italy-based research group.
Radar images indicate shafts and chambers
The research team used synthetic aperture radar (SAR) data collected from orbiting satellites to analyze variations in subsurface density beneath the pyramid. By processing reflected radar signals through mathematical modeling, they created composite images that appear to show structural anomalies beneath the monument.
According to their interpretation, eight cylindrical shafts extend hundreds of meters deep into the limestone bedrock beneath the Pyramid of Chephren. At greater depths, the radar patterns indicate the presence of two large cubic chambers. The team also suggests the existence of five vertical cavities within the pyramid itself.
However, the researchers emphasize that these conclusions are based on image interpretation and not on direct physical investigations such as drilling or ground-penetrating radar.
Academic response was measured. Egyptologists and geologists note that the Giza Plateau is largely composed of limestone bedrock, which naturally contains cracks, cavities and cave systems. Several natural cavities beneath the pyramids have been documented in previous geological studies.
Because limestone terrain often contains underground voids formed over thousands of years, some experts suspect the radar signatures may reflect natural geological formations rather than man-made structures. Without excavation or on-site validation, distinguishing between man-made shafts and natural cavities remains a challenge.
Still, the debate has gained traction online, where alternative history commentators have made connections between the proposed subterranean features and references to the Duat, the underworld, described in ancient Egyptian funerary texts. Others have speculated about connections to prehistoric Anatolian sites such as Taş Tepeler, although there is currently no archaeological evidence for such associations.
The satellite radar study has broadened the discussion about what might be beneath the Pyramid of Khafre, but has not resolved long-standing questions about the geology and construction of the Giza complex.
Until physical investigation confirms the claims, the proposed underground shafts and chambers remain part of an ongoing scientific and public debate that highlights both the promise and limitations of remote sensing technology in archaeology.
