A new claim that a vast underground city lies beneath the Pyramids of Giza has sparked controversy among archaeologists, with some calling it a major discovery while others dismiss it as speculation.
Italian researcher Professor Corrado Malanga from the University of Pisa and his team say radar scans have detected an extensive subterranean network below the pyramids. Their findings suggest the presence of deep vertical shafts, winding staircases, and what appears to be a complex water system more than 2,000 feet (610 meters) underground. The researchers even propose that this hidden structure could contain the fabled Hall of Records—a legendary archive believed by some to hold ancient Egyptian knowledge.
“As we refine the imaging further, we believe we’ll uncover evidence of a full underground city,” the researchers stated during a press briefing in Italy. 
However, many experts have cast doubt on these claims. Radar specialist Professor Lawrence Conyers from the University of Denver argues that the scanning technology used—satellite-based ground-penetrating radar—cannot penetrate to such extreme depths. He called the findings “highly exaggerated,” although he acknowledged that smaller hidden structures could exist beneath the pyramids.
Renowned Egyptian archaeologist Dr. Zahi Hawass also rejected the study outright, stating that it lacks any scientific foundation. “There is no evidence to support these claims,” he told The National, adding that a discovery of this magnitude would require physical excavation and thorough validation.
The research, conducted by Malanga and his colleagues Filippo Biondi and Armando Mei, focused on the Khafre Pyramid, one of the three great pyramids of Giza. However, their study has not yet been published in a peer-reviewed journal, leading to further skepticism among experts.
The pyramids, built around 4,500 years ago along the west bank of the Nile, continue to captivate historians and researchers alike. While the idea of a lost underground metropolis fuels public intrigue, definitive proof remains absent. Until further evidence emerges, the mystery of what—if anything—lies beneath Giza endures.
