For the first time, researchers have digitally recreated a ‘machine’ used by Ancient Egyptians to guard the Great Pyramid. The device was allegedly used to keep looters from accessing the King’s chamber. But the real question is: Was the device set into place to keep thieves from going in, or was it placed into position to keep something from exiting the Pyramid?

According to archaeologist Mark Lehner, the ancient Egyptians used a ‘primitive machine’ to protect the Kings Chamber inside the Great Pyramid of Giza from looters.

A trap that was found in the nineteenth century, even though ‘primitive’ was effective. The invention managed to block the corridor that led towards the room with up to SIX giant blocks once the builders of the pyramids were at a safe distance.

The defensive system is described in a new episode of Unearthed shown on the Science Channel last week. The news was reported initially by Live Science.

The new episode explains how the builders of the Pyramids installed grooves into a small room that was located just outside the Kings Chamber where the Pharaoh’s body would be placed.

Lehner, who has been excavating at Giza for over thirty years, explains how the curious anti-theft system worked for the first time.

Even though researchers had knowledge of the mechanism previously, it was digitally recreated for the first time ever in a television program.

Specifically, the animation shows exactly how the device closed off the passageway leading towards the King’s Chamber –the alleged resting place where the mummy of the Pharaoh Khufu was supposed to lay— preventing treasure hunters from accessing the eternal resting place of the Pharaoh.

The builders incorporated ‘grooves’ into a smaller room just outside the chamber. Afterward, granite slabs would have been placed into them when the work was finished in order to restrict access to the chamber.

In addition, the builders used three other granite blocks which were slid down a ramp to the passageway which prevented anyone from accessing the inner sanctuary. In addition to the King’s Chamber, the Great Pyramid of Giza also has two other large chambers, which are today called the Queen’s Chamber and the Subterranean Chamber.



In the documentary shown on the Science Channel, Dr. Legners says:

“Here Khufu’s builders designed a line of defence against anyone who would enter the King’s chamber had they got this far. These grooves and protrusions are not decorative. They are part of a very primitive machine.”

However, many researchers believe the system was ineffective and that it did not stop treasure hunters from looting the tomb. Archaeologists discovered the tomb empty, and the only thing that was left behind was a fractured red stone that made up the Pharaoh’s sarcophagus. Researchers speculate –they are not 100 % certain— that the tomb was looted shortly after it was completed.

Since the mummy of Pharaoh Khufu was never found within the King’s chamber, and there are also no records that mention any sort of tomb or Pharaoh Khufu, the questions that we raise is: What was the intricate ancient device actually protecting? Was it keeping something from going inside the chamber? Or is there a possibility that the machinery was placed into position in order to prevent ‘SOMETHING’ from exiting the Pyramid?

According to Dr. Lehner, Khufu’s eternal resting place was looted sometime after the collapse of the Old Kingdom, around 2134BC. However, other researchers suggest that the tomb of Pharaoh Khufu still remains undiscovered and is still somewhere inside the Pyramid, in an undiscovered chamber within the 2.3-million-stone-block monument.

  1. Not buying the explanation. Even the fact that the pyramid was made for Khufu is based on slim, almost nonexistent evidence. They have found graffiti in some small crawl space that seems to mention Khufu, although even that is not conclusive. For my money, one small piece of “evidence” doesn’t prove anything. As far laying over 2 million 2 ton and larger stones (some carved from granite weighing between 25 and 80 tons) in twenty years? Do the math. If they worked 24 hours every day (no lights remember, only torches) they would have had to have laid a stone every 4 and a half minutes (approx). The logistical probability is just too far fetched. The timing is so tight that it leaves no margin for any error, act of nature (like say a cold or flu epidemic among the workers) or other unknown contingent or delay. As a man who has done his share of hard, back breaking work (and who is paying the price in my older years) I find the archaeological explanations too convenient and lacking understanding of just how truly hard this task must have been. Theories often lack one ingredient that can’t be recreated in a laboratory or simple “in situ” tests…..sweat.

    Many have their theories and I suppose that one day we’ll know the real truth, but for now I’m a skeptic. Actually I’m more like a person from Missouri whose state motto is “Show Me!”

  2. According to the Great Zecharia Sitchin, the Great Pyramid was in effect, a prison for Marduk. Although not built to BE a jail, per se. But in a pinch….

    “It was then, we believe, that the sealing of the Great Pyramid was completed. Leaving Marduk alone in the King’s Chamber, the arresting gods released behind them the granite plugs of the Ascending Passage, irrevocably blocking tight all access to the upper chambers and passages.”–
