The Tunnel of Efpalinus (or the Eupalinian Aqueduct) is a monument dedicated to the science of geometry.

The tunnel “manages” to glorify geometry, as did the Temple of Artemis, one of the Seven Wonders of the ancient world. The Tunnel of Eupalinus is the work of a genius in geometry, at a time when geometry had just made its first “celestial” leap.

On the occasion of its first opening for the public and our recent visit (we actually walked the tunnel all the way), we would like to make known some facts, most of which are quite impressive yet unknown to the many!
