Advanced Scans at Khafre Pyramid
In 2022, scientists Corrado Malanga of the University of Pisa and Filippo Biondi of the University of Strathclyde used Synthetic Aperture Radar (SAR) tomography to study the Khafre Pyramid on the Giza Plateau. Their findings revealed five identical subsurface structures near its base.
Vertical Wells and Spiral Pathways
The radar scans uncovered eight vertical cylindrical wells beneath the structures. Each well was surrounded by a spiraling pathway, descending to a depth of 648 meters. These pathways converge into two cube-shaped structures, each measuring 80 meters on each side.
Network Beneath All Three Pyramids
This intricate system is estimated to stretch two kilometers beneath all three Giza pyramids. The structures were not visible using traditional excavation methods and had not been documented before this radar-based study.
Research and Excavation Plans
The findings were detailed in a study published on arXiv in 2022. As of March 2025, the research team expressed interest in further excavation. However, approval from Egyptian authorities remains pending due to restrictions on non-traditional archaeological work at the site.
