Learn more Scientists and engineers are still debating how the Egyptian pyramids were built, but the most widely accepted theory is that the Egyptians used sledges, rollers, levers, and ropes to move large stone blocks up ramps greased with water or wet clay. The ramps were made of an embankment of brick, earth, and sand that increased in height and length as the pyramid rose. The blocks were then dragged and lifted into position. Britannica How did the Egyptians build the pyramids? - Britannica The most plausible one is that the Egyptians employed a sloping and encircling embankment of brick, earth, and sand, which was increased in height and length as the pyramid rose; stone blocks were hauled up the ramp by means of sledges, rollers, and levers. en.wikipedia.org Egyptian pyramid construction techniques - Wikipedia Most of the construction hypotheses are based on the belief that huge stones were carved from quarries with copper chisels, and these blocks were then dragged and lifted into position. Disagreements chiefly concern the methods used to move and place the stones. National Geographic What are the Pyramids of Giza—and who built them? Dec 20, 2023 — Scientists and engineers are still debating exactly how the pyramids were constructed. It's generally believed that the Egyptians moved massive stone blocks to the heights along large ramps, greased by water or wet clay, using a system of sledges, ropes, rollers, and levers. Here are some other techniques that may have been used: Quarry to construction site: Most blocks came from nearby quarries, but special stones were transported from distant locations. Wetting the sand: The sand in front of the sled may have been wetted to reduce friction. Causeways: The blocks may have been dragged on causeways made of slaked lime or tafla, a local clay. The builders may have first established true north, then worked out the other directions from that. They may have found true north by taking a sighting on a particular star in the northern sky, observing the star's rising and setting, and marking its appearance and disappearance on an artificial horizon.
