There are a few conjectures when it comes to the enigmatic construction process of the Great Pyramid of Giza. One of the oft-mentioned ones pertains to the ramp theory, which simply puts forth the scenario that the massive ancient structure was built by raising ramps (or mounds) all around it. Essentially, according to this hypothesis, once the foundation was laid, makeshift ramps were constructed around the core structure to haul and position the stone blocks on top of it. As the structure gradually rose in height, the ramps were raised higher to accommodate the building blocks.
Now while this sounds like a simple solution in theory, in practical circumstances, the inclined plane of these ramps would roughly require a mile of construction for the 480-ft pyramid. However, this time around, beyond engineering hypotheses, researchers have found actual evidence for a ramp at the site of Hatnub, an ancient quarry in the Eastern Desert of Egypt, near Luxor. In an excavation project carried out by jointly by the French Institute for Oriental Archaeology based in Cairo and the University of Liverpool, the archaeologists identified the remnants of an entire system that was used for hauling heavy alabaster stones at a relatively steep angle.
