The ancient town of Phocis, at the temple of Apollo on Mount Parnassus. It is said to be the "navel of the world".

Greek sanctuary dedicated to the god Apollo

an ancient Greek city on the slopes of Mount Parnassus; site of the Temple of Apollo

The shrine where the famous oracle lives, sacred to Apollo

One of the most important oracular temples (temples where the gods could be questioned) in the ancient Greek world was that dedicated to the god Apollo at Delphi. The priesthood would have gained great geo-political knowledge in the course of relaying questions to Apollo and dispensing the god's answers, and in this way gained considerable influence over much of the Aegean. That Croesus could hardly have gone to war without approval from this Greek oracle is an indication of the intensity of international relations.

Delphi (Greek Δελφοί — Delphee) is an archaeological site and a modern town in Greece on the south-western spur of Mount Parnassus in a valley of Phocis. In ancient times it was the site of the most important oracle, dating into prehistoric times as a site for the worship of Gaia and in classical times, converted to that of the god Apollo.
