Was Egypt's first pyramid built with hydraulics? The theory may hold water
A new theory suggests the Step Pyramid of Djoser may have used a hydraulic system for lifting stones, though critics question its feasibility and call for further research on construction methods.

A new theory suggests that the Step Pyramid of Djoser, Egypt's first pyramid built around 4,700 years ago, may have utilized a hydraulic system for construction. Researchers propose that a water-powered elevator inside the pyramid helped lift heavy stone blocks, which could weigh up to 2,500 kilograms. This theory, presented by a team led by Xavier Landreau, posits that controlled water flow into a shaft allowed a platform to raise and lower stones during construction. The model is based on data from the pyramid's internal features and surrounding landscape, including a structure known as Gisr el-Mudir, which could have captured floodwater. Critics, however, question the feasibility of this hydraulic system, arguing that the water source may not have been sufficient and that the stones used were smaller and easier to transport than those in later pyramids. They also note the lack of historical evidence for the proposed lake and hydraulic lift. Landreau acknowledges the need for further research to better understand the pyramid's construction methods.
- The Step Pyramid of Djoser may have used a hydraulic system for stone lifting.
- The theory is based on a model of water flow and internal pyramid features.
- Critics argue the hydraulic system's feasibility due to insufficient water sources.
- The stones used in Djoser's pyramid were smaller and easier to transport.
- Further research is needed to clarify the construction methods of the pyramid.
