Satellite radar study claims vast underground structures beneath the Giza Pyramid
Reports emerging in March 2025 have drawn attention to fresh claims about hidden structures beneath the Pyramid of Khafre on the Giza plateau. An Italy-based research group, working with satellite radar imagery rather than ground excavation, says it has identified large underground features extending deep below the monument. The team used Synthetic Aperture Radar data gathered from orbiting satellites and processed it to produce composite images of subsurface density. Their interpretation points to vertical shafts and sizable chambers cut into the bedrock. The findings have not been verified through an on-site investigation. For now, they remain part of an ongoing debate about remote sensing methods, data interpretation and the long-studied geology of the Giza plateau in Egypt.
Synthetic aperture radar used to map subsurface features beneath the Pyramid of Khafre
The researchers relied on Synthetic Aperture Radar, often shortened to SAR. This technology sends radar signals from satellites in orbit. The signals reflect off the ground and are recorded, then processed using mathematical modelling. Variations in density and structure can appear as patterns in the final images.Based on this study, “What Really Lies Beneath the Pyramids?”, the team believes it can see eight deep cylindrical shafts beneath the pyramid. These are said to descend hundreds of metres into the limestone bedrock. At the lower end, the images appear to show two large cubic chambers. Inside the pyramid itself, five vertical voids are also suggested. It is an interpretation of patterns rather than a physical survey.
Claims generate online interest and academic caution
The announcement moved quickly across social media platforms. Alternative history commentators gave it prominence. Videos and commentary circulated widely within days.Academic reaction has been more restrained. Egyptologists point out that satellite radar imagery can be complex. Image processing may produce shapes that resemble structures without confirming their material nature. Without drilling, excavation or ground-penetrating surveys, it is difficult to establish what lies below.
Natural caves already exist beneath the Giza Plateau
The Giza plateau is not solid stone throughout. Limestone bedrock in the area contains natural cavities and fissures. Some caves have been explored in previous decades. Earlier geophysical surveys also detected voids in certain areas beneath the pyramids.Because of this, some researchers suggest the radar signatures could represent natural formations rather than engineered shafts. The difference matters. Geological voids are common in limestone terrain. The present claims do not yet clearly separate between natural and artificial origins.
Speculation links findings to ancient myths and older cultures
Beyond the technical debate, some writers have drawn connections between the proposed structures and ancient Egyptian ideas of the Duat, the underworld realm described in funerary texts. Others go further, suggesting links with prehistoric sites in Anatolia associated with the Taş Tepeler tradition.These associations remain speculative. No archaeological evidence currently connects the Giza plateau to those earlier cultures. For now, the radar study adds another layer to the discussion around Khafre’s pyramid. It does not settle it.
