Scientists are close to solving the construction of the world's first pyramid: what was the secret of the Egyptians

For many years, the ancient Egyptian pyramids have been one of the most confusing mysteries for scientists, as they have not been able to investigate how the workers of the time built stone structures without the use of large machinery. However, a recent study conducted by French scientists suggests that our ancestors used a complex hydraulic system.

The first structure, known as the Djoser pyramid, appeared in the African state more than 4,700 years ago on the Saqqara plateau. Since it is located near the disappeared arm of the Nile River, archaeologists believe that the Egyptians used a water source to build the structure, Live Science reports.

The world's first pyramid looks like a six-tiered tetrahedral triangle with many steps. The structure, made of stone and clay, covers an area of about 330,400 cubic meters and reaches a height of 62 meters. Researchers at the Paleotechnical Institute in France believe that the ancient Egyptians used a hydraulic system that included a dam, a water treatment plant, and a freight elevator to build the structure. They assure that the Gisr el-Mudir fence, located around the structure, was used to keep water and sediment from the Nile.

"This is a groundbreaking discovery. Our research can completely change the perception of the status of the built pyramid. Before this study, there was no consensus on what these structures were used for. One possible explanation was that they were used for funeral purposes. We know that this is already a subject of debate," said Xavier Landreau, the lead author of the study.

Scientists believe that for the system to work, water from the Nile flowed to a dam that was 2 kilometers long and 15 meters wide. Here, the liquid from the river was to be filtered from the sediment and sent to the Deep Trench treatment plant. The design was to include several mud storage basins to prevent damage to the system.

Scientists assume that the next step was to direct the river's flow into an underground pipeline located under a special elevator at a depth of 28 meters. The force of the water accumulated in the reservoir served as a key element that allowed heavy stones to be lifted and lowered down the mine.

"The elevator would have played a crucial role in allowing water to fill the main shaft. It's a really gigantic structure that shows that water was the fuel for building the pyramid. The elevator had filling and emptying cycles that allowed the stones to rise to the building level, like a volcano," said one of the scientists.
