In March 2025, a team of Italian and Scottish researchers claimed to have discovered a vast underground city beneath Egypt's Pyramids of Giza using Synthetic Aperture Radar (SAR) technology. They reported identifying extensive subterranean structures, including eight vertical shafts descending approximately 650 meters, interconnected chambers, and spiral staircases. The researchers suggested that these findings could significantly alter our understanding of ancient Egyptian architecture and urban planning.

However, these claims have been met with skepticism from the archaeological community. Renowned Egyptian archaeologist Zahi Hawass dismissed the assertions, stating that no such discoveries have been made beneath the Pyramid of Khafre. He emphasized that the methods used by the researchers are not scientifically validated and labeled the claims as "fake news." Additionally, experts in radar archaeology have questioned the feasibility of detecting structures at such depths using current SAR technology. Professor Lawrence Conyers from the University of Denver highlighted that radar pulses cannot penetrate to the depths claimed, suggesting that the findings are likely exaggerated.

As of now, there is no credible evidence supporting the existence of a vast underground city beneath the Pyramids of Giza. The archaeological community continues to rely on peer-reviewed research and validated methodologies to explore and understand Egypt's ancient structure.

The existence of a major underground city beneath the Pyramids of Giza is not yet supported by any reliable evidence. Peer-reviewed studies and proven techniques are still used by the archeological community to investigate and comprehend Egypt's ancient architecture.
