On a clear day you can see them from the city. The three pyramids of Giza are Khafra, Menkaure, and Cheops, not forgetting the immutable Sphinx, which seems to watch over and protect them. Built from 2750 BC, they are truly impressive when you're at their feet. Allow between half an hour and an hour's drive from downtown Cairo to reach the Giza Plateau.
In general, they are only open to group visitors in turn, and at certain times. Check out booking conditions before you go and above all, book a guide. As a keen Egyptologist, he will explain, among other things, that archaeologists have not yet pierced the mysteries of the pyramids and that a new study mission has just begun. Without altering the buildings, using aerospace technologies such as thermal infrared cameras, drones, and laser scanners, French and Egyptian researchers are trying to discover the secret of their design. The mathematics and architectural principles that served to build them, however, remain a riddle… like that of the Sphinx.
