In the main chamber of the Great Pyramid, there is a granite coffer. What appears to be an entirely normal feature of this type of structure is actually something extraordinary. The reality is that the coffer is, in fact, a finely carved granite piece.
It was not possible for the Egyptians to fit the large piece through the passage, suggesting that the Great Pyramid could be built around the coffer instead of the other way around.
Power Of The Nile
It may make sense that the Pyramids of Giza could have been built so close to the Nile because any civilization would find being close to a source of water to be an advantage.
It is believed, however, that there was a much more spiritual reasoning behind this placing. Supposedly symbolizing the realm of the dead, the Pyramids of Giza were located on the west bank of the Nile, exactly where the sun sets.
Cooler On The Inside
It is indisputable how the Egyptians actually were ahead of their time. This can first be seen in the finding that the structures were constructed using a ball and socket mechanism to prevent earthquake damage.
Secondly, the pyramids were built so accurately that, although the harsh arid heat would be on Egyptian structures, the temperature inside the pyramids remained cool at 20 degrees Celsius.
Mysterious Mortar
One of the greatest mysteries around the Great Pyramid is the mortar which was used to "glue" the blocks. The truth is that no archeologist has traced the origins of this mortar or the material used to make it to this day.
The only thing scientists know for sure is its chemical composition. Though they couldn't reproduce the composition, it is believed to be harder than the actual stone.
Royal Rooms
Two of the most common theories are at completely opposite ends of the spectrum. The first theory is worldly in nature, suggesting that the void acts as a "construction gap" and a platform for builders to move from one part of the building to another.
However, the second theory suggests that it was the path between the chamber of the King and the chamber of the Queen. This could also suggest something else.
