New discovery beneath Egypt's Sphinx fuels theory of ancient underground city built 38,000 years ago
The mystery of a 'underground city' beneath Egypt 's pyramids has intensified after scientists revealed new scans showing a shaft plunging below the Great Sphinx. Italian researchers, who made waves earlier this year with claims of vast structures hidden beneath the Pyramid of Khafre, now say they have identified a colossal vertical shaft leading and two chambers below the Sphinx. The findings were presented at the recent Cosmic Summit in North Carolina, a gathering known for exploring alternative theories about ancient history. While mainstream archaeologists have slammed the work as unscientific and speculative, the team insists their latest scans point to something extraordinary. Filippo Biondi, a radar expert from University of Strathclyde in Scotland and co-author of the research, told 'These findings strongly support the hypothesis that the Giza Plateau conceals a vast subterranean complex, potentially indicative of an extensive underground city.' The scans detailed a massive shaft surrounded by a spiral-like staircase, decedending from the center of the Sphinx's base and down into two square structures, one at 2,000 feet and another 4,000 feet underground. Armando Mei, an Egyptologist and co-author of the study, noted that similar underground features have now been detected beneath all three major pyramids, suggesting a unified architectural blueprint. 'The discovery proves that the Giza Plateau was engineered long before the dynastic era, possibly around 36,400 BCE, as my research suggests,' he added. If confirmed, the findings could dramatically rewrite the history of ancient Egypt, challenging the long-held belief that the pyramids were built solely as royal tombs, and hinting instead at a forgotten civilization with advanced engineering skills. The iconic Giza pyramids and the Great Sphinx have long been hailed as marvels of ancient engineering, built roughly 4,500 years ago with breathtaking precision and scale that still baffle experts today. But the researchers are shaking up that timeline, suggesting these legendary monuments may rest atop far older, hidden structures that could predate known history by tens of thousands of years. It all began in March when the team announced four massive shafts and chambers were found under the Pyramid of Khafre using a type of sonar technology. They employed cutting-edge SAR Doppler Tomography, a technique that uses satellite radar to detect tiny seismic movements. By analyzing radar signals are and the timing or pattern of those signals when they bounce back, the team was able to create 3D maps revealing hidden subsurface structures. The technology has been published in a peer-reviewed journal. However, latest work by Corrado Malanga from Italy's University of Pisa, Biondi and Mei has not yet been published in a scientific journal for the review of independent experts. They plan to publish a study in 2026. 'Our geophysical surveys beneath the Great Sphinx uncovered pillar-like formations remarkably similar to those beneath the Khafre and Menkaure pyramids,' explained Biondi. 'Even more compelling, our tomographic imaging revealed two large chambers nearly 2,000 feet below the surface.' The two massive chambers, each measuring 131 feet by 131 feet, appear to be connected by an underground shaft, according to recent findings. The data collected also points to a network of hidden structures below the surface, possibly part of a vast underground city, potentially as expansive as the entire Giza Plateau itself. Mei explained that their theory of a lost city draws from ancient Egyptian texts, particularly Chapter 149 of the Book of the Dead, which references the '14 residences of the city of the dead.' 'It describes certain chambers and some inhabitants of the city. That is why we believe it could be Amenti [realm of the dead], as described in ancient texts,' he said. 'Of course, we must be certain, but we believe this could be the case because the pyramids are located exactly where the texts say. 'The texts state that the pyramids were built on top of the city, sealing its entrance.' Biondi added that the mysterious chambers found more than 4,000 feet below the pyramids may be linked to the legendary Hall of Records. The Hall of Records is a mythical chamber said to lie beneath the Great Pyramid or the Sphinx, reputed to house lost wisdom about ancient civilizations. Armando Mei (center) and his team, which includes Corrado Malanga (right) and Filippo Biondi (left), took the world by storm last month when they discovered shafts and chambers more than 2,000 feet below the surface. Despite its enduring allure, there is no solid evidence proving the Hall of Records exists. The team proposes that an advanced civilization originally built the complex, but was destroyed around 12,000 years ago by a 'divine flood' triggered by an asteroid impact. According to their theory, the pyramids are the lone surviving 'megastructure' from this ancient society. Alternate historians, including Graham Hancock, a frequent guest on Joe Rogan's podcast, have long suggested that a sophisticated prehistoric civilization was wiped out by a global cataclysm, possibly a comet strike. This theory holds that the catastrophic floods and upheaval erased most traces of this civilization, with survivors passing down critical knowledge of astronomy, engineering, and sacred architecture to later cultures such as the ancient Egyptians. The researchers now hope to gain permission from Egyptian authorities to excavate beneath the Giza Plateau and put their findings to the test, potentially rewriting the story of human history. 'We have the right. Humanity has the right to know who we are because, right now, we don't,' Biondi said.

Experts Dismiss Viral Report Claiming Hidden City Beneath Egypt's Pyramids
Last Updated: In ground-breaking research, a group of scientists earlier claimed to have discovered evidence of a second underground city beneath Egypt's Giza Plateau. The history of the Pyramids, located in Egypt, still remains a mystery, notably for their construction. While the ancient Egyptians were in charge of building them, the exact methods, tools, and resources employed are still being researched and debated today. In a ground-breaking research, a group of scientists earlier claimed to have discovered evidence of a second underground city beneath Egypt's Giza Plateau, connecting the Khafre Pyramid to other surrounding sites. But now, top archaeologists have refuted the previous claims, calling it 'unscientific.' As per a Daily Mail report, experts used Synthetic Aperture Radar (SAR) tomography to discover what they believe to be a huge subterranean complex connecting the Khafre, Khufu, and Menkaure pyramids, as well as the Great Sphinx. Filippo Biondi, a radar expert at the University of Strathclyde, stated that these buildings are '90 per cent likely" to be connected. 'We firmly believe that the Giza structures are interconnected, reinforcing our view that the pyramids are merely the tip of the iceberg of a colossal underground infrastructural complex," Biondi earlier told CNN. Also, the previous report claimed that the researchers had identified vertical shafts that went as far as 2,000 feet below the Khafre pyramid. According to them, the shafts could date back to a civilisation 38,000 years ago, considerably older than the pyramids, which were built around 4,500 years ago. Egypt's pyramids are ancient masonry buildings designed primarily as tombs for pharaohs and their consorts during the Old and Middle Kingdom periods. Over 130 pyramids have been discovered in Egypt, with many of them part of larger complexes. The Great Pyramid of Giza, built for Pharaoh Khufu, is the largest and most famous and was once the tallest man-made structure in the world. First Published:

Controversial researchers claim second ‘hidden city' found beneath Egypt's pyramids: report
The researchers who claimed to have found a vast underground city beneath Egypt's Great Pyramids doubled down on the wild theory Tuesday by saying they've found a second 'hidden city.' Italian and Scottish scientists studying the pyramid of Khafre say their radar system has uncovered another subterranean complex linking the structure to the Khufu and Menkaur pyramids, as well as the Great Sphinx, the Daily Mail reported. Filippo Biondi, a radar expert from Scotland's University of Strathclyde, claimed there was a 90% chance that the structures were connected — despite the research being lambasted by experts who slammed the findings as 'fake' and utterly lacking in scientific basis. Advertisement 4 A team of researchers believe they've found two underground cities connecting the Great Pyramids of Giza. 4 The team claims a layout of the land and radar scan reveal massive, vertical shafts beneath the pyramids. Khafre Project 'We firmly believe that the Giza structures are interconnected, reinforcing our view that the pyramids are merely the tip of the iceberg of a colossal underground infrastructural complex,' Biondi told the Mail. The team's research, which has yet to be peer-reviewed or published in any scientific journal, made waves back in March when they claimed to have found 2,000-foot-long vertical shafts underneath the Khafre pyramid. Advertisement The scientists still haven't presented a purpose for what the structures were used for, only speculating that they were built by a lost ancient civilization around 38,000 years ago. Egypt's three Great Pyramids, however, were only built around 4,500 years ago. 4 The research connects with a theory that an ancient civilization existed beneath the wonders of the world. Khafre Project Advertisement The scientists also claim they made the discoveries using satellite synthetic aperture radar (SAR) technology, which led Dr. Zahi Hawass, a renowned archaeologist and Egypt's former minister of antiquities, to slam the whole research as 'bulls–t.' SAR technology can only penetrate the ground by at most 10 inches, which would make it impossible for researchers to find data on shafts 2,000 feet below ground, Hawass and other experts explained. 'The claim of using radar inside the pyramid is false, and the techniques employed are neither scientifically approved nor validated,' he told the National, slamming the project as 'fake news.' 4 Egypt's pyramids remain a fascination for many around the world. REUTERS Advertisement Despite the scientific consensus, the team's research has reignited interests in ancient Egypt and speculation that there are still many secrets waiting to be uncovered under the sands. Fanatics of ancient Egypt continue to search for the fabled Hall of Records, a hidden library believed to be underneath the pyramid complex or the Great Sphinx containing resources of information about the ancient people. The rumor originated from self-proclaimed clairvoyant Edgar Cayce, an American who claimed in the 1930s that refugees from Atlantis built the library to preserve their history.

Scientists uncover second 'hidden city' beneath Egypt's Giza pyramids
Scientists who claimed earlier this year to have found a massive subterranean city under the Pyramids of Giza now say they have unearthed a second city. The team of Italian researchers, who claimed they found huge underground structures below the Khafre pyramid in March, now say they've found more evidence of a second 'hidden city'. These new subterranean structures, apparently found underneath the Mankaure pyramid, could 'prove' the existence of a massive subterranean complex which links the three Giza pyramids thousands of feet below the surface. The announcement sparked controversy amongst archaeologists and Egyptologists, who said the unverified claims are 'a total scam' and argued the technology used isn't able to penetrate deeply enough into the ground. The Pyramids of Giza, along with the Great Sphinx, are located west of Egypt's capital Cairo, and the methods used to build the huge structures are still shrouded in mystery thousands of years on. Filippo Biondi, co-author of the research, told MailOnline their data shows a 90% probability that the Menkaure shares the same pillars as Khafre. 'Objective analysis of the tomography data, which, as experimental measurements, strongly indicate that the structures we identified beneath Khafre are also present under Menkaure,' Filippo said. 'We firmly believe that the Giza structures are interconnected, reinforcing our view that the pyramids are merely the tip of the iceberg of a colossal underground infrastructural complex. 'This network likely consists of a dense system of tunnels linking the main subterranean structures. 'The measurements reveal pillar-like structures with consistent characteristics. 'Given that Menkaure is smaller than Khafre, we believe the number of pillars is likely even but fewer than those under Khafre.' It's estimated there are eight pillars under Khafre pyramid, which are estimated to be more than 2,000ft long and feature spiral-like structures. The researchers say finding similar pillars underneath Mankaure pyramid support their theory that a 'megastructure' hides thousands of feet underneath the sands. When asked about the purpose of the hidden structures, Filippo said: 'At this stage, we're still gathering information to thoroughly study the matter, but we can confidently say that the operation of this structure likely involves the natural elements: air, water, fire and earth. More Trending 'Discoveries like these under Menkaure challenge us to rethink our understanding of ancient Egyptian history and humanity's past, opening new perspectives on our origins and capabilities.' Archaeologists estimate the three Pyramids of Giza are about 4,500 years old, but Filippo and his team theorise these pillar structures could have been built by a lost ancient civilisation about 38,000 years ago. They suggest a highly advanced prehistoric society was wiped out by a global cataclysm, possibly caused by a comet impact, around 12,800 years ago. But some have drawn comparison to conspiracy theories that it was in fact aliens who built the pyramids.
