Italian Researchers Map Large Cubic Chambers 600 Meters Beneath Khafre's Pyramid

An international team of Italian researchers released updated findings in early 2026 detailing anomalous subterranean structures located more than 600 meters beneath the Pyramid of Khafre at Giza, Egypt. The primary detection involves large, precisely defined cubic chambers, each measuring approximately 80 by 80 meters, mapped using advanced geophysical survey techniques.

The deep-level investigation is currently under scrutiny by the global archaeological community due to its potential to significantly alter the understanding of Old Kingdom engineering and funerary practices. The research group has drawn a preliminary connection between these newly mapped voids and the legendary 'Hall of Records,' a repository of ancient Egyptian knowledge often linked to the nearby Sphinx.

While the existence of the Hall of Records remains speculative within mainstream Egyptology, the sheer scale and geometric regularity of the detected 80x80 meter cubic spaces suggest an intentional, non-natural formation at this significant depth. The initial data collection phase reportedly concluded in late 2025, preceding these early 2026 confirmations.

The technical methodology employed by the Italian group is central to the report's credibility, reportedly moving beyond conventional ground-penetrating radar to utilize more sophisticated subsurface imaging, potentially involving muon tomography or advanced gravimetric analysis to map structures at such extreme depths. Mapping structures at over 600 meters below the desert floor represents a significant technological achievement in non-invasive exploration.

The implications for Egyptian history are considerable; structures of this magnitude, if confirmed as man-made, would necessitate a reassessment of the logistical capabilities and architectural ambitions of the Fourth Dynasty builders responsible for Khafre's monument. The ongoing analysis seeks to differentiate between natural geological features and structures exhibiting the high degree of organization implied by the cubic specification. The Italian researchers have indicated plans for a more detailed report later in 2026, which is expected to include cross-validation from other international geophysical survey organizations.
