Pyramids not built as we thought: 'forgotten force' contributed to building grand mystery

When we think about the Egyptian pyramids, we envision endless ramps, ropes pulled by hundreds of men and stone blocks dragged in the blazing sun. It's a powerful, almost cinematic image that's accompanied us for decades. But what if, in reality, it wasn't like this? What if behind one of humanity's greatest undertakings was a silent and invisible natural force that we have always underestimated: water.

The pyramids are not just old. They are precise, massive, almost stubbornly perfect. Built more than 4,500 years ago, with millions of stone blocks weighing an average of two and a half tonnes, they still give modern engineers headaches. No electricity, no steel, no engines. And yet, they're still standing. For a long time, we have wondered how that was possible. Today, a new scientific hypothesis suggests that we may have been looking in the wrong direction.

How we have always imagined the construction of the pyramids

For a very long time, there seemed to only be one answer: ramps. Earthen structures, straight or spiral, along which workers would have pulled the blocks up on sleds, using levers, ropes and impressive manpower. This is a logical thought, repeated in textbooks and documentaries, but one that still leaves many questions unanswered, especially when looking at the oldest and most monumental pyramids.

Over time, other theories have emerged: internal ramps hidden in the pyramids, counterweights systems, gradual lifting techniques. Some modern scans have revealed abnormal spaces, but none of these hypotheses has ever provided a sound agreement. However, one thing we know for sure is that the pyramids were not built by slaves, but by specialised workers, organised, fed and supported by a highly efficient state apparatus. And yet, even taking all that into account, the question remains: was it really only human power?

Water as a secret ally

The new hypothesis comes from the study of a very specific structure: the Djoser pyramid in the Saqqara necropolis, one of the oldest pyramids of the Old Kingdom. Here,  according to a group of researchers led by Xavier Landreau, traditional ramps might not have been the main solution.

The idea is as simple as it is disruptive: the ancient Egyptians would have used a hydraulic system to lift the stone blocks, a kind of water lift integrated into the structure of the pyramid itself. Not an improvised trick, but a complex system based on collecting, controlling and utilising water from natural watercourses and seasonal rains.

According to this reconstruction, water was directed to basins and canals, collected and then fed into vertical shafts in the pyramid. The water pressure would have allowed the material to be raised, drastically reducing the human effort required. If confirmed, this idea would radically change our point of view with regards to engineering in ancient Egypt.

Traces in the landscape

A number of archaeological features in the area make this theory less fanciful and a lot more concrete. Indeed, not far from the pyramid lies a large stone structure, the Gisr el-Mudir, which for years was interpreted as a defensive structure. Today, however, many researchers are noticing that its features seem to better fit a dam or a water system for level management.

Moreover, around the pyramid, traces of canals, settling basins and reservoirs are coming to light that seem to meet the needs of a full-fledged hydraulic system, which could not only collect water, but also direct and purify it. In the pyramid itself, some architectural details prompt thought: granite blocks, limestone structures connected to clay and locking mechanisms reminiscent of inflow and outflow systems.

In particular, the northern shaft of the pyramid shows a configuration that researchers believe is consistent with a hydraulic lifting system. It's not definitive evidence, but rather a series of clues that when put together tell a different story from the one we grew up with.

This theory is not  accepted by the entire scientific community yet. Many archaeologists remain cautious, recalling that, especially for the pyramids of Giza, the traditional ramps remain the most solid hypothesis. But the value of this new reading lies elsewhere. It reminds us that the ancient Egyptians knew nature thoroughly and knew how to work with it, using resources such as water in an imaginative and sustainable way.

As we rethink energy, natural resources and human ingenuity, this story also speaks to the present. Perhaps the pyramids are not only a monument of the past, but also an invitation to look at what we have always taken for granted once again.
