Underground City Beneath the Pyramids? - That's Nothing New

Recently, the theory that an underground city lies beneath the Sphinx and the Pyramids of Giza has gained traction again. But is this a legend or reality?

Our goal here is to show both sides of the coin: from science to myths and ancient stories. I myself am fascinated by mystical and ancient books and have traveled to many places that have shown me a reality that is, to say the least, unusual. It is impossible to ignore the stories, drawings, sacred texts and independent studies that invite our investigation.

This will be our promise here: let's investigate together this incredible subject of one of the most mysterious ancient civilizations in the world – Welcome to Secret Egypt!

Structures under the pyramids? That's nothing new.

About a month ago, the internet went down with the “discovery” of, to say the least, suspicious structures under the pyramid of Chephren. I won't go into too much detail here about the veracity of the research, but I want to reflect with you exactly on the main subject, which is the presence of hidden structures that have not yet been discovered.

A network of tunnels, halls and hidden chambers would hold secrets of the ancient Egyptian civilization or even of previous civilizations. As a relatively skeptical explorer, I do not easily align myself with theories that lack solid evidence. I am also quite accustomed to the internet where many people are chasing clicks with fantastical stories and other people's illusions.

One thing I know - Structures inside or under the pyramids are nothing new. Research with various technologies, carried out since the 90s, has detected anomalies under the Sphinx and also in areas close to the Great Pyramid. In 2017, a study published in Nature had also reported the discovery of a huge unknown cavity inside the pyramid of Cheops. The scientific community and mystics were excited by the idea that there is still much to be revealed beneath these monumental structures.

But what I really want to talk about here is that long before modern science outlined these discoveries, mystical and esoteric traditions already spoke of hidden chambers, tunnels and libraries buried beneath the pyramids. Rosicrucians, theosophists, hermeticists and visionary authors such as Edgar Cayce treated these underground structures as places of initiation and repositories of ancestral knowledge. Symbolic maps, oral legends and even ancient works that we will talk about in a little while here, suggest the existence of “internal temples”, some visible, others invisible to the common eye, but accessible only to those who hold the spiritual or initiatory key.

Anyway, how much of all this can really be considered?

Edgar Cayce and the Atlantean Records

Edgar Cayce, known as "the sleeping prophet", stated in several of his readings that there would be a chamber called the "Hall of Records" beneath the Sphinx, containing the records of Atlantis and the true past of humanity. According to Cayce, this chamber would be discovered in the late 20th or early 21st century, and would reveal a connection between Egypt and a lost civilization that predated the flood.

Many may question the seriousness of Edgar Cayce, but in most cases the myth drives exploration. Many researchers and curious people have been inspired by Cayce to conduct radar searches around the Sphinx. Some of these investigations have even detected subterranean geometric anomalies, which has further fueled the debate about possible hidden structures.

Today, there are several studies underway, and wells and paths are closed to the curious eyes of the general public. The big question is: have they really found something relevant that would shake up history, or is there simply no interesting evidence yet?

H. Spencer Lewis and the Secret Archives of Egypt

In 1936, H. Spencer Lewis, a Freemason and one of the emperors of the Ancient and Mystical Rosacrucian Order (AMORC), published the book The Symbolic Prophecy of the Great Pyramid, which contains an interesting diagram of a completely unknown part of the Sphinx with a path to the pyramids.

In his drawing, Lewis also mentions a circular temple, a secret staircase behind the Stele of Thutmose, and hidden passages to the Great Pyramid and the Nile River. According to his accounts, ancient traditions used the path and the temple for initiatory purposes that are preserved to this day in the great mystery schools.

Speaking of the Stele of Thutmose, this one was very controversial due to its design suggesting an underground space beneath the Sphinx. But, to this day, at least nothing has been officially released.

Herodotus and the Lost Labyrinth of Egypt

Now I'm going to get in the time machine and go back to the 5th century BC, when the Greek historian Herodotus described in his "Histories" a vast Egyptian labyrinth with thousands of rooms and courtyards. This construction was not beneath the pyramids, but was located near Lake Moeris, and would have amazed many other historians who visited it. Some say that it would have surpassed even the pyramids in grandeur. Herodotus claimed to have visited part of the structure, guided by local priests, and was impressed by its complexity.

For centuries, the Labyrinth described by Herodotus was considered a legend, but excavations in the Hawara region revealed underground structures that partially coincide with his account. Although far from the pyramids of Giza, this discovery reopens the discussion about the existence of large complexes hidden under dozens of meters of sand accumulated over centuries or millennia.

Tunnel after Tunnel: The Forgotten Underground of Giza

In 1817, explorer and Egyptologist Giovanni Caviglia was one of the first to undertake systematic excavations at the Great Sphinx of Giza. Hired by British consul Henry Salt, he not only cleared parts of the monumental sculpture, but also explored tunnels that ran from the base of the Sphinx and the adjacent plateau. According to reports, Caviglia and his team explored underground tunnels, discovering chambers connected by narrow corridors. Although these reports are not recognized by official archaeology, they indicate that it is possible that underground structures had been discovered as early as the 19th century—long before modern theories gained popularity.

Fast forward to the end of the 20th century, excavations led by renowned Egyptologist Zahi Hawass and American researcher Mark Lehner provided new information about the subsoil of the Giza Plateau. Using modern technology, the research revealed the presence of natural cavities and possible excavated tunnels, especially around the Sphinx. One of the most discussed finds was a vertical shaft behind the body of the Sphinx that led to an underground chamber—later sealed by Egyptian authorities, but not before generating intense debate about its purpose and origin.

Although the official explanation attributes these structures to ancient attempts to collect water or religious cults, their layout and architecture still raise more questions than answers.

Curiosities: Sacred Measurements and Scientific Coincidences

Regardless of the existence of underground cities, there are fascinating aspects of the architecture of the pyramids that suggest an advanced knowledge of mathematics and astronomy. Several scholars have drawn attention to the proportions of the Great Pyramid of Giza, whose measurements seem to incorporate the constant pi, the golden ratio, and relationships with the circumference of the Earth.

I'll mention a few here just for you to remember and reflect on:

The pyramid has a total perimeter of 921.4 meters and a height of 146.5 meters.
This distance is very close to half a minute of latitude at the equator, or 1/43200 of the circumference of the earth.
Multiplied by its height (with the tip) the result is the distance from the earth to the north pole with a difference of only 120m.
In inches, the perimeter of the pyramid is 36524.2, that is, 100x the number of days in a year (100 years).
The height of the pyramid coincides with the distance from the earth to the sun on a scale of 1 billion.
The latitude of the pyramid of Giza is 29.9792458°N, while the speed of light is 299,792,458 meters per second.
Thirty Empire States could be built with its blocks. It is estimated that they took 20 years to build (1.5 Empire State buildings per year).

A rare book worth reading on this subject is The Great Pyramid: Its Divine Message by D. Davidson and H. Aldersmith. Its authors argue that the pyramid’s dimensions contain hidden codes and premonitions. Although many of these calculations involve speculative interpretations, the fact that so many mathematical “coincidences” are embedded in such an ancient structure continues to intrigue scientists, historians, and even mystics.

Conclusion

I am particularly skeptical about recent studies that claim a lost city beneath the pyramids. However, I do believe that there are still many things beneath the Giza plateau to be revealed in the right time and space. Many cases have already proven true where the myth was proven by science decades or even centuries later when humanity was ready.

One thing I am sure of: some were there and kept quiet, while others wrote their stories in a way that respected the religious, social and evolutionary context of the time. But, if you so wish, today, you can also have access to this knowledge through the right books, travel and ancient wisdom. After all, the truth is out there.
