The Serapeum in Egypt near the pyramid of Djoser in Sakkara is one of the most mysterious places on earth. It is a sort of underground bunker, first entered by Auguste Mariette in 1851. It is hundreds of meters long with 24 large side-chambers. These side chambers contain enormous granite sarcophagi.They were cut from a single piece of rock and weigh between 60 and 80 tons, and about 20 tons for t

he lid. It is believed that these sarcophagi were intended as final resting places for sacred bulls, but there is no evidence for it. All but some sarcophagi were empty. A few contained a smelly mass of smashed bone fragments wrapped in bitumen.

Apart from the mystery of whether these giant granite boxes served as last resting places for sacred bulls or not, a greater mystery is how people ever fabricated these monstrous things.

They are so large and so smoothly finished that even today there is hardly any equipment anywhere in the world to cut such huge blocks out of a mountain, hollow them out with sharp interior corners and polish the inner and outer sides to astonishing evenness..The lid, also extremely even, is perfectly square with the inside walls of the sarcophagus. To be square, these inside walls must be perfectly parallel at a distance of 1.5 m and 4.5 m. What’s more, the topside of the box is a perfect plane that is square to the sides.

This precision, in combination with the gigantic proportions, is beyond comprehension. The equipment isn’t available yet and it would cost an enormous effort to build these – it makes no sense! Extreme high-tech precision stone cutting, drilling and polishing technology was applied here. Who did this, how and why?
