Archaeologists Discover Underground ‘Anomaly’ Beneath Egypt’s Giza Pyramids

By: Beth Moreton | Published: May 28, 2024

It isn’t usual for research teams to find underground tunnels underneath pyramids, but that is exactly what a research team in Giza has found at an ancient Egyptian burial site near the Giza pyramid complex.

While this discovery is an anomaly, it is an important one. The survey has enabled the archaeologists to discover some important archaeological remains that give a deeper understanding of the history there.

The Giza Pyramids Have Strange Secrets

Archaeologists have been trying to uncover centuries of strange secrets buried underneath the Giza Pyramids for years.

The secrets archaeologists have been able to unearth include the methods of construction used, information about the burial place for ancient Egyptian kings and queens, and the use of limestone. They have also been able to learn things from the artwork on the walls inside the pyramids.

The Western Cemetery Is an Important Burial Place

For this particular excavation, the archaeological team decided to look at the western cemetery which is next to the Giza pyramids.

The team chose this area, as it is important in ancient Egyptian history. Many of ancient Egypt’s royalty and high-class officers were buried there, meaning that the excavation was always likely to show something exciting and potentially some new information about ancient Egyptian life.

Mastabas were also found in this area. Many of these had been excavated in previous years; however, the ones in the western cemetery hadn’t.

The mastaba is a tomb that has a flat roof and rectangular structure on the ground surface. It is made out of either limestone or mud bricks, and they have vertical shafts that are connected to underground chambers.

Archaeologists Used Geophysical Techniques

When they realized that something could be underneath the area surrounding the Giza pyramids, the archaeologists involved in the study began using geophysical techniques to uncover it.

This included using ground-penetrating radar (GPR) and electrical resistivity tomography (ERT) to help the archaeologists detect any possible structures underneath the ground’s surface. This gives them a more accurate idea of what is there and where they are before excavating.

Two Underground Structures Were Connected

When the archaeologists began the excavation process, they discovered two structures, one shallow and one deep, connected to one another, which they believe to be an anomaly.

The archaeologists believe that the shallow structure was previously used to enter the deeper structure. The deeper structure was highly electrically resistive and was 10 meters deep. The shallow structure was roughly two meters deep.

The Structures Were Filled With Sand

One thing the archaeologists did notice was that the structures had been filled with sand. This means that after the structures had been constructed, someone had gone back and filled them up with sand.

As there was highly electrically resistive material in the deeper structure, this could be a mixture of sand and gravel, including sparse spacing or air voids. However, neither the GPR nor ERT were able to identify exactly what this was.

Excavations at the Giza Pyramids Are Happening

The archaeological team decided to use the GPR and ERT scanning methods first to see what might be there so as not to excavate an ancient burial site when they were unsure if there was anything of importance there.

However, now they know that there is something underneath the ground that could be of archaeological importance, they have decided to excavate the area, which is currently ongoing. This is so the team can establish the purpose of the underground structures.

Structures Are Not a Natural Phenomenon

These excavations are particularly important as the archaeologists can tell that the structures are not natural phenomena as the shape of the structures is too sharp to have formed naturally.

The archaeologists are hoping that if they excavate the area they will find out more information about how it was built, who is buried there, and any other information they can gather about life here during the ancient Egyptian period.

A Surprising Discovery Under the Giza Pyramid

These scans of the area took place between 2021 and 2023. Around the same time, in March 2023, archaeologists uncovered a hidden corridor underneath the Giza pyramid.

To discover this, they used an endoscopic camera and a technique known as cosmic-ray muon radiography and found the corridor was 30 feet long and 7 feet wide. It is also believed there could be other corridors within the pyramids that are yet to be uncovered.

The Giza Pyramid Anomalies Are Unknown

While the results of the excavations are still unknown, it is hard for archaeologists to know what these anomalies discovered within the structures are. Currently, all anyone can do is put in a few rough guesses until more information has been uncovered.

Along with guessing that it could be a mixture of sand and gravel or an air void, some researchers have also guessed it could be vertical walls made of limestone or shafts leading to a tomb structure.

Lack of Superstructures

Despite being surrounded by important structures, this area has never been investigated or excavated before because there are no superstructures in that specific area. These are structures above the ground.

However, as the archaeologists have uncovered something more spectacular and interesting than they ever could have thought, they are now waiting with bated breath to see what these excavations will uncover. Will they see once and for all what these anomalies really are?

Technological Advancements in Archaeology

Modern technology is revolutionizing archaeology, with tools like ground-penetrating radar (GPR) and electrical resistivity tomography (ERT) leading the way. These advanced techniques allow archaeologists to detect underground structures with unprecedented accuracy.

Limitations of Current Technologies

While GPR and ERT have transformed archaeological practices, they come with limitations. These techniques can sometimes produce ambiguous results due to varying soil compositions and other environmental factors.

The Role of Environmental Factors in Preservation

Egypt’s dry desert climate plays a crucial role in preserving ancient structures and artifacts. The arid conditions slow down the decomposition process, allowing materials to remain intact for millennia.

Impacts of Climate on Archaeological Methods

The harsh climate of Egypt necessitates specific archaeological methods tailored to protect both the site and the researchers. Extreme temperatures and sandstorms can impede progress, requiring robust planning and adaptation.
