A group of researchers set out to confirm the existence of an extensive underground city beneath the Giza Pyramids in Egypt, positioned more than 4,000 feet deep. Their latest analysis supports their initial claims.
The team, based in Italy, revealed groundbreaking findings last week, asserting they had identified wells and chambers reaching heights of several thousand feet beneath the Khafre Pyramid.
If proven accurate, this discovery could challenge established beliefs about Egyptian and human history. However, other experts have discredited the findings, labeling them as unsubstantiated and scientifically unfounded.
Researchers said they determined ‘a confidence level well above 85 percent’ that the ‘structures identified beneath the Pyramid of Khafre, as well as those beneath other pyramids on the Giza Plateau,’ exist.
The wells and chambers were identified by sending ‘high-frequency electromagnetic waves’ into the subsurface, and the way signals bounced back allowed researchers to map structures beneath the pyramid.
The team used ‘a specialized algorithm’ to process the data and create the images that showed what looked like wells with spiral formations leading to enormous chambers.
They cross checked the structures with known architectural forms, ‘specifically those accessible to us today, such as the Pozzo di San Patrizio in Italy,’ Niccole Ciccole, the project’s spokesperson, shared with Dailymail.com.
Professor Lawrence Conyers, a radar expert at the University of Denver who focuses on archaeology and was not involved in the study, said: ‘To make correlation confidence levels there needs to be something to correlate to or compare to.Â
‘What could that be here? Without that, these percentages are meaningless scientifically.’

Scientists on a mission to prove a ‘vast city’ sits more than 4,000 feet below Egypt ‘s Giza Pyramid have released a new analysis they say proves the findings to be true
However, Professor Conyers suggested that it is conceivable that small structures, such as shafts and chambers, may exist beneath the pyramids, having been there before the pyramids were built, because the site was ‘special to ancient people.’
He highlighted how ‘the Mayans and other peoples in ancient Mesoamerica often built pyramids on top of the entrances to caves or caverns that had ceremonial significance to them.’
The team claimed they found eight wells and two enormous enclosures more than 2,000 feet below the base of the Khafre pyramid and ‘an entire hidden world of many structures’ another 2,000 feet below those
‘I am skeptical of the deeper claims. If their ‘algorithms’ can do what they say (I can’t comment on those), then perhaps this will hold up,’ Professor Conyers said.
‘A ‘well’ or ‘tunnel’ is what I would expect under a pyramid.’
The work by Corrado Malanga from Italy’s University of Pisa, Filippo Biondi with the University of Strathclyde in Scotland and Egyptologist Armando Mei has not yet been published in a scientific journal for the review of independent experts.Â
The team sent the analysis to DailyMail.com, where they admitted ‘further validation is recommended through additional tomographic scans and in-situ verification.’
To determine if anything was hiding below the Pyramid of Khafre, they sent high-frequency waves (similar to how radar works) into the ground beneath the pyramid.

When the waves smashed into something below the surface, they bounced back to the surface, and by looking at how the frequency of these waves changed, scientists could tell what kind of materials were underground.
However, Dr Zahi Hawass, Egypt’s former minister of antiquities, told The National: ‘The claim of using radar inside the pyramid is false, and the techniques employed are neither scientifically approved nor validated.’
The team said while they ‘have the utmost respect for Egyptologists,’ their ‘findings are based on objective measurements obtained through advanced radar signal processing.’Â
After gathering the data, researchers used a special algorithm that turned the information into vertical images of the ground beneath the pyramid, capturing the first look at the hidden structures.
One of the images ‘exhibits a vertically elongated feature with varying intensity distributions, suggesting the presence of a deep well-like formation,’ said Ciccole who has 25 years of experience in forensics.Â
‘The upper portion of the well reveals patterns indicative of potential helical or spiral formations, which could correspond to a staircase or a sloped passageway.’
She added that high-intensity reflections seen in the images suggested ‘structured discontinuities that may align with step-like features.’Â
‘Preliminary estimations indicate that the well extends significantly underground, with notable signal variations at multiple depths,’Â Ciccole said, explaining it could indicate different materials or chambers at various levels.
‘The helical feature aligns with descriptions of spiral-descending shafts found in other ancient structures.’
Professor Conyers said agreed in that spiral-descending shafts are found in other ancient structures, such as the Pyramid of Unas and certain Middle Kingdom tombs.

The team also believes the shafts and enclosures are around 38,000 years old. The pyramids were built around 4,500 years ago

Researchers believe there are other structures reaching more than 4,000 feet below the surface. The scans captured structures extend along the northern side with a tuning fork shape
‘We estimate a correlation confidence of 85 to 90 percent with the hypothesis of a helical staircase within the well,’Â said Ciccole.
The team also believes the structures were built around 38,00 years ago, which predates the oldest known man-made structure of its kind by tens of thousands of years.
They based the claim on ancient Egyptian text that they interpreted as historical records of a pre-existing civilization that was destroyed during a cataclysmic event, but Professor Conyers said: ”That is a really outlandish idea.’
He added that at that time in human history people ‘were mostly living in caves’ 38,000 years ago.Â

‘People did not start living in what we now call cities until about 9,000 years ago,’ he said. ‘There were a few large villages before that but those only go back a few thousand years from that time.’
But researchers explained there was likely a pre-existing civilization that was destroyed during a cataclysmic event.Â
The event is a theory about a massive asteroid hitting Earth around 13,500 years ago, causing global climate change and extinction worldwide.
While ice cores in Greenland and other geological data in the Atlantic Ocean point to such an event, scientists have largely dismissed it due to never finding an asteroid crater.
Researchers believe that ancient Egyptian text seen as myths are actually historical records of life before the cataclysmic event.Â
They said chapter 149 of the Book of the Dead describes 14 dwellings of the divine which team interprets as describing remnants of an advanced civilization existing before dynastic Egypt.
Ciccolo said the team also used the Turn King List, or Royal Canon, which is an ancient Egyptian document that features the name of kings, including gods and demigods, who supposedly ruled Egypt before the first recorded dynasties.
Researchers believe that the god and demigods were actually living kings long before the first recorded pharaohs.
Ciccolo said these ancient texts ‘provide a whole series of references that a pre-existing civilization’ lived in the region before ‘a cataclysmic event.’
