70 years ago today, on December 9th 1955, the Council of Europe adopted the flag we all recognize . Hidden in plain sight for seven decades is a perfect geometric secret.

Central to the flag are 12 five-pointed stars. Take these stars, align them point to point, and you’ll get a dodecahedron - one of the 5 Platonic solids that have fascinated humanity since Ancient Greece.

It's a remarkable coincidence. Many designs were proposed before 1955, including variants with 1 or 15 stars. But only 12 stars create this hidden geometric harmony.
