The Great Pyramid of Giza Has 8 Faces, Not 4 – A Discovery That Redefines the History of Egyptian Architecture

Most people think they know what the Great Pyramid of Giza looks like—four massive triangular faces meeting at a point, forming a nearly perfect square-based pyramid. But what if we told you it’s actually an eight-sided structure? That’s not a typo.

Thanks to modern technology and a bit of rediscovery, scientists have confirmed that each face of the Great Pyramid is subtly split down the middle, making a total of eight distinct planes. And it’s not an accident, erosion, or a trick of the light. It was part of the original design.

Let’s cut into this ancient engineering mystery that’s baffling researchers and igniting curiosity all over again.

Discovery

The idea that the pyramid had more than four sides was first noticed in 1927 by a British pilot flying over Giza. He captured images showing a strange shadow pattern on the pyramid’s faces, particularly during sunrise or sunset. But the world didn’t take notice at the time. Fast forward to today, and researchers from Kanagawa University in Japan have confirmed the finding using modern aerial photography and 3D scans.

Under certain lighting conditions—like during the equinoxes—each face of the pyramid reveals a subtle inward bend. This creates a visible central line that divides each face into two angled sections. It’s something you can’t see from the ground, which is probably why it stayed hidden for so long.

Structure

This eight-sided design isn’t a flaw. It’s a feature. According to physicist Akio Kato, the pyramid’s faces indent inward by roughly 11 degrees. That slight dip may not look like much on paper, but it plays a critical role in the pyramid’s stability. It allows the massive stone blocks to compress together more tightly, offering resistance against earthquakes, erosion, and even structural shifting over time.

Let’s put it into perspective: this thing has stood the test of time for more than 4,500 years, and it’s still standing tall. That level of durability doesn’t happen by accident.

Purpose

So why would the ancient Egyptians go through the trouble of designing the pyramid this way?

The most practical theory is reinforcement. The slight concavity strengthens the structure, helping it withstand the natural forces acting upon it. This would explain why the Great Pyramid has lasted while others have crumbled or needed restoration.

But there’s another theory—one that ties into the Egyptians’ obsession with the sky. Some believe the eight-sided design was meant to be seen from above. This makes sense when you consider how often Egyptian monuments were aligned with celestial events. Think about the alignment with Orion’s Belt, the solstices, and other astronomical points. Could the pyramid’s faces have been designed to reflect light differently, or signal something during certain times of the year?

Design

The level of precision in the pyramid’s construction is nothing short of jaw-dropping. The Egyptians used simple tools—ropes, wooden levels, copper chisels—and yet created a structure with millimetre-level accuracy. That’s why the pyramid’s sides are almost perfectly aligned to the cardinal directions, and why the concavity can’t be chalked up to human error.

Even without modern technology, they accounted for stress distribution, weight management, and even optical illusions. Some experts think the concave design may also make the pyramid look perfectly flat from a distance—another testament to their genius.

Comparisons

Let’s look at how the Great Pyramid stacks up to other pyramids of its time:

Pyramid	Structural Design	Condition	Unique Feature
Great Pyramid of Giza	8-sided concavity	Almost intact	Precision alignment, symmetry
Meidum Pyramid	Straight sides	Collapsed	Early attempt at true pyramid
Step Pyramid of Saqqara	Terraced steps	Restored	First large-scale stone building
Bent Pyramid of Dahshur	Changed angle	Partially intact	Shift in angle mid-way

Clearly, the Great Pyramid had something the others didn’t—possibly because of engineering details like the eight-sided faces.

Mystery

Even after centuries of study, the Great Pyramid still holds onto its secrets. These recent findings just add another layer to the mystery. Were these indentations meant to communicate with the gods? Were they symbolic? Practical? A bit of both?

No one knows for sure, but what’s undeniable is the genius behind it. These builders were thinking in dimensions we’re only now beginning to understand, without the help of computers, CAD programs, or drones.

And just when we think we’ve uncovered all there is to know about this ancient wonder, a new side—literally—emerges from the shadows. So maybe the real magic of the pyramid isn’t just in its age or size, but in its ability to keep us guessing.
