## Why do pyramids face north?

In the third millennium BC, no star sat at the north pole. Instead, **all the stars in the north sky rotated around an imaginary point marking the north pole**. Experts thought the ancient Egyptians might have watched a single star circle this imaginary point and aligned their pyramid with the circle’s centre.

## Do the pyramids follow the golden ratio?

The most famous monuments of ancient Egypt are the Great Pyramids of Giza. Believed to have been constructed around 4,600 years ago, **these pyramids were built around the golden ratio**, long before the Greeks and the Parthenon. The largest of the pyramids in Giza contains the use of phi and the golden ratio.
