Delphi

Delphi, in legend previously called Pytho (Πυθώ), was an ancient sacred precinct in central Greece. It was the seat of Pythia, the major oracle who was consulted about important decisions throughout the ancient classical world. The ancient Greeks considered the centre of the world to be in Delphi, marked by the stone monument known as the Omphalos of Delphi. The term omphalos was the Greek word for "navel".
