A ‘sarcophagus’ hidden more than 600 feet below the surface in Egypt is the latest discovery from the team that uncovered a ‘vast city’ beneath the Giza pyramids.

Italian researchers told DailyMail.com that they identified an unknown chamber under the Tomb of Osiris, which is believed to be a symbolic burial site dedicated to the Egyptian god of the afterlife.

Last week, the team announced the discovery of wells and chambers more than 2,000 feet below the Khafre Pyramid. If confirmed, these findings could rewrite human history.

Many independent experts have called the claims ‘outlandish,’ noting that using radar pulses to create images deep below the structure lacks scientific basis.

An image produced by the technology revealed the known levels within the Tomb of Osiris, descending 114 feet below the surface, along with a vertical shaft followed by three distinct steps.

It also detected a previously unknown structure, which ‘appears to reach an empty chamber’ 656 feet below the surface.

‘There is also a sarcophagus (?), which remains surrounded by running water,’ said the team.

However, Professor Lawrence Conyers, a radar expert at the University of Denver who specializes in archaeology and was not involved in the study, said the technology cannot penetrate to such depths.

‘Maybe 30 or 40 feet, depending on the wavelength they’re using. But they’re not even telling us that. All of this is very speculative,’ he added

The work by Corrado Malanga of Italy’s University of Pisa, Filippo Biondi of the University of Strathclyde in Scotland, and Egyptologist Armando Mei has not yet been published in a scientific journal for independent expert review.

Researchers told DailyMail.com that they released the new image ‘in response to concerns raised regarding the effectiveness’ of the technology used to identify an ‘entire world of structures’ more than 4,000 feet beneath Khafre.

Niccole Ciccole, the project’s spokesperson, said: ‘This presents the tomographic analysis of the Tomb of Osiris—an interior structure that is extensively documented—demonstrating how satellite radar tomography has successfully replicated its features.

‘The analysis extends to a depth of approximately 656 feet in this specific case.’

To conduct the new analysis, the team used the same process as in their previous work uncovering shafts and chambers beneath the Khafre Pyramid, employing Synthetic Aperture Radar (SAR).

They sent high-frequency waves into the ground beneath the Tomb of Osiris.

When the waves struck underground structures, they bounced back, and by analyzing how their frequencies changed, scientists could determine the type of materials present.

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 stated that while they ‘have the utmost respect for Egyptologists,’ their ‘findings are based on objective measurements obtained through advanced radar signal processing.’

After collecting the data, researchers applied a specialized algorithm to convert the information into vertical images of the ground beneath the Tomb of Osiris.

Niccole Ciccole, a forensic expert with 25 years of experience, explained that the images captured dark areas within the shaft on the third level, suggesting the presence of additional structures below.

‘Deeper still, a black area, possibly a small (or actually, large) room, is visible,’ she added.

‘This area descends an estimated 328 to 656 feet, based on preliminary pixel calculations. This previously undocumented feature is detectable using SAR, which accurately replicated it.’

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. Pictured are the eight wells under the pyramid

The first discovery took the world by storm last year when the team announced they had found eight wells and two enormous enclosures more than 2,000 feet beneath the Khafre Pyramid—along with unknown 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 eight descending wells measure between 33 and 39 feet in diameter and extend at least 2,130 feet below the surface.

The results also revealed staircase-like structures wrapping around each of the wells, which Ciccole said appeared ‘to serve as access points to this underground system.’

The wells fed into two massive rectangular enclosures, each measuring approximately 260 feet per side.

During a news briefing last week, the team also announced the discovery of a water system beneath the platform, with underground pathways leading even deeper into the earth.

They believe this could be evidence of a possible hidden city more than 4,000 feet below the pyramid.

The Giza pyramids, believed to have been built around 4,500 years ago, remain a marvel of engineering due to their immense scale and precision—an achievement that continues to puzzle scientists today.

However, the Italian researchers claimed that the hidden structures, spanning 4,000 feet, are approximately 38,000 years old — which predates the oldest known man-made structure of its kind by tens of thousands of years.

The team has based these claims on ancient Egyptian text that they interpreted as historical records of a pre-existing civilization that was destroyed during a cataclysmic event.

Professor Lawrence Conyers, a radar expert at the University of Denver who focuses on archaeology and was not involved in the study, told DailyMail.com: ‘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. 

‘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.’
