Theogefyro. The word is Greek and it means bridge made by God. The rapids of the river Kalamas together with nature and time pierced the rock and opened a passageway which through the years took the shape of a bridge. As most physical events were interpreted as a result of divine intervention the natural bridge was named Theogefyro.
Of course the traditions and legends could not be missing as for anything that was difficult to interpret divine intervention created ways of saving people.
