5DELPHI
182 km / 113 miles north-west of Athens, on the south-western slope of Mount Parnassus is Delphi, home to the Sybil or Oracle of Delphi. According to the Greek myths, Zeus determined to locate the centre of earth by sending two eagles to find it, one flying east and the other west. In time, their paths crossed over what is now Delphi. Obviously, this must be the center of the earth and so the city was founded.
