Claims of underground city under pyramids get a boost as scientists detect secret chambers under Great Sphinx

Mystery around the discovery of an ancient city under the Egyptian pyramids continues to intensify. The two scientists who revealed earlier this year that they had found massive chambers and towers under the Pyramid of Khafre, now say that there is a colossal vertical shaft and two chambers below the Sphinx. They spoke about their latest scans at the Cosmic Summit in North Carolina. The researchers said that the Giza Plateau is hiding a vast subterranean complex, as revealed by new scans, Mail Online reported. They believe this hints at the existence of a massive underground city. According to their findings, a spiral-like staircase descends from the centre of the Sphinx's base. There are two square structures underneath - one at 2,000 feet and another at 4,000 feet - and the staircase goes down to these chambers.

Eight vertical cylinder-shaped structures under pyramid

What started with one pyramid now extends to all three pyramids in Giza. This suggests that an extensive city lies under the pyramids, with chambers, staircases, pillars and more. Armando Mei, an Egyptologist and co-author of the study, said, "The discovery proves that the Giza Plateau was engineered long before the dynastic era, possibly around 36,400 BCE, as my research suggests." In March, the two scientists from Italy and Scotland said that sonar scans showed a city spanning more than 6,500 feet, and 10 times larger than the pyramids. They reportedly found eight vertical cylinder-shaped structures extending more than 2,100 feet below the pyramid, and more unknown structures 4,000 feet deeper.

Great Sphinx is hiding pillars, staircase and chambers

The team created 3D maps by analysing radar signals and timing them based on their bounce back. The maps revealed hidden subsurface structures under the pyramids. "Our geophysical surveys beneath the Great Sphinx uncovered pillar-like formations remarkably similar to those beneath the Khafre and Menkaure pyramids," Filippo Biondi from the University of Strathclyde in Scotland said. The findings are yet to be published in a journal to be peer reviewed, which they plan on doing in 2026. "Even more compelling, our tomographic imaging revealed two large chambers nearly 2,000 feet below the surface," Biondi added. The two chambers under the Sphinx measure 131 feet by 131 feet and seem to be connected by the shaft. Another revelation is the network of hidden structures below the surface that could be a part of the vast underground city. The scientists believe this entire city could be equal to the entire Giza Plateau in size.

Apocalypse destroyed the ancient Egyptian city?

The pyramids of Giza are believed to have been built 4,500 years ago. However, if the theory of a sophisticated, vast, ancient city is proven, then the whole history of Egypt changes. Some researchers say that an ancient advanced civilisation was wiped off 12,000 years ago by a flood triggered by an asteroid or comet impact. The pyramids are the only components that exist from that society. There are three pyramids - Khufu, Khafre and Menkaure - in the Giza complex built on the west bank of the Nile River in the name of pharaohs. Khufu is the oldest one and is also known as the Great Pyramid. It is 480ft tall and 750ft wide at its base. Khafre is the middle pyramid.
