The great pyramids of Gizeh are the final survivors of the original Seven Wonders of the World. The pyramids are currently a major tourist attraction not only for their majesty, but also because of the impressive ancient building techniques that were required in the construction of the man-made mountains. Archeologists and scholars agree in some aspects of the construction of the great pyramids, such as quarry work or transportation, but disagree in their theories of how the stones were maneuvered and laid at the actual construction site.
The construction of the great pyramids began with extracted large limestone blocks from the Gizeh plateau. Slave workers led by master builders would use wooden or copper tools, such as mallets, chisels, and wedges, to cut the stone from the quarry. Then, because the stone was to be used for royal tombs, each cut stone was heavily refined, made to be perfect and as close to identical as possible. This was to aide in appearance as well as the strength of the pyramid itself.

The stones were then transported to the construction site using field animals or on rollers and sleds. Where scholars largely disagree is on how the stones were transported up the pyramid during construction. One point of view is that the Egyptians used long ramps on all four sides of the pyramid, which would help reduce the slope during the haul. It is theorized that the builders used ramps made of a combination of gravel, mud, and wood to create a smoother carry. Another theory is that ramps were only built on one side of the pyramid. It makes more sense that the Egyptians would reduce the amount of work as much as possible, so I believe that the ramps were built on all sides of the pyramid, which would allow delegation of labor and increase daily productivity.
