New Subterranean Find Beneath Egypt’s Sphinx Supports Ancient City Theory

New Discoveries Beneath the Giza Plateau Challenge Established Beliefs

Recent findings beneath the Giza Plateau have sparked renewed interest in the mysteries surrounding ancient Egypt. Scientists have uncovered what appears to be a massive vertical shaft and two chambers located below the Great Sphinx, raising intriguing questions about the history of this iconic site. These discoveries were presented at the recent Cosmic Summit in North Carolina, an event that brings together experts exploring alternative perspectives on ancient history.

The research team, led by Italian scientists, has been investigating the area for some time. Their work has revealed a complex network of subterranean structures that could potentially change our understanding of ancient civilizations. The scans show a spiral-like staircase leading down from the center of the Sphinx’s base into two square-shaped chambers, one situated 2,000 feet underground and another at 4,000 feet.

Filippo Biondi, a radar expert from the University of Strathclyde in Scotland, highlighted the significance of these findings. He stated that the evidence strongly supports the idea that the Giza Plateau conceals a vast subterranean complex, possibly indicating the existence of an extensive underground city. This theory challenges the traditional view that the pyramids were solely built as royal tombs.

Armando Mei, an Egyptologist and co-author of the study, noted that similar underground features have now been detected beneath all three major pyramids. This suggests a unified architectural blueprint, which could imply that the Giza Plateau was engineered long before the dynastic era. According to Mei, this could date back to around 36,400 BCE, a period far earlier than previously believed.

If confirmed, these findings could dramatically rewrite the history of ancient Egypt. They challenge the long-held belief that the pyramids were built solely as royal tombs and instead hint at a forgotten civilization with advanced engineering skills. The Giza pyramids and the Great Sphinx are renowned for their breathtaking precision and scale, constructed roughly 4,500 years ago. However, the researchers suggest that these monuments may rest atop far older, hidden structures that could predate known history by tens of thousands of years.

The research began in March when the team announced the discovery of four massive shafts and chambers 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 and the timing or pattern of those signals when they bounce back, the team was able to create 3D maps revealing hidden subsurface structures. This technology has been published in a peer-reviewed journal.

However, the 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. Biondi explained that their geophysical surveys beneath the Great Sphinx uncovered pillar-like formations remarkably similar to those beneath the Khafre and Menkaure pyramids. More compellingly, their 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.” This text describes certain chambers and some inhabitants of the city, leading the researchers to believe it could be Amenti, the realm of the dead, as described in ancient texts. They argue that the pyramids are located exactly where the texts say, suggesting that they 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. This mythical chamber is said to lie beneath the Great Pyramid or the Sphinx, reputed to house lost wisdom about ancient civilizations. 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, 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. Biondi emphasized the importance of uncovering the truth, stating, “We have the right. Humanity has the right to know who we are because, right now, we don’t.”
