For thousands of years, the pyramids of Giza have stood above one of archaeology's greatest mysteries. But in 2025, a claim emerged that potentially made the mystery considerably larger. Researchers using satellite-based Synthetic Aperture Radar (SAR) said they had detected enormous structures beneath the Pyramid of Khafre — including vertical shafts, chambers and possible interconnected underground features extending far below the Giza Plateau. The claims quickly spread around the world, with some reports describing an enormous underground "city" beneath the pyramids. But there is a crucial question: Did the radar actually detect what the researchers claimed it detected? The Khafre claim The research was associated with Italian researcher Corrado Malanga and radar specialist Filippo Biondi. Their approach involved analysing SAR data from satellites and, rather than simply looking at conventional radar images, examining extremely small movements and signals associated wit...

Beneath the bustling streets of modern Italy lies an astonishing hidden world. Far below Rome, Naples, Orvieto and countless other cities stretches a labyrinth of tunnels, catacombs, aqueducts, chambers, quarries and forgotten passageways created over thousands of years. While millions of visitors admire Italy's famous monuments above ground, relatively few realise that an equally fascinating realm exists beneath their feet.  Some of these underground structures were engineering masterpieces that supplied water to entire cities. Others served as burial grounds, military refuges, places of worship or secret escape routes. Many remain only partially explored, and new discoveries continue to emerge from beneath Italy's ancient soil. These subterranean networks reveal a remarkable story of Roman ingenuity, survival and adaptation. They also fuel enduring mysteries about lost chambers, hidden treasures and forgotten sections of the ancient world that may still await discovery. The R...

Beneath the surreal landscape of Cappadocia in central Turkey lies a hidden world that seems more at home in a fantasy novel than in reality.  While tourists marvel at the region's famous fairy chimneys, cave churches and hot-air balloons, an even more astonishing mystery lies underground: vast subterranean cities capable of sheltering entire communities. Carved deep into soft volcanic rock, these underground labyrinths contain homes, churches, wells, kitchens, stables, storage chambers and ventilation systems. Some descend more than 80 metres below the surface and may once have housed tens of thousands of people.  Even today, archaeologists continue to debate exactly how these remarkable complexes were developed and how they functioned during times of danger. A Hidden World Beneath the Earth Cappadocia contains dozens of known underground cities and hundreds of smaller cave complexes carved into the region's unique volcanic tuff.  The soft rock is relatively easy to exca...
