No structure in the world is more mysterious than the Great Pyramid of Giza.

It is hard to imagine that the monument in homage to Cheops was built from 2.3 million blocks of stone, on average, each weighing more than two tons, and that they were carved with simple copper tools.

It’s not less impressive to realize that its sides are precisely aligned with the cardinal points and that none exceeds the others by more than five centimeters. Not to mention that with its original 146.58 meters, the Great Pyramid has remained the highest human construction in the world for nearly 4,000 years – until the central spire of the Cathedral of the Virgin Mary of Lincoln is completed in 1310.

But all these superlatives are of no help to us to elucidate the mysteries it conceals.
