Delphi is a UNESCO World Heritage site
Located amidst breathtaking scenery in central Greece, Ancient Delphi is the site of the Sanctuary and Oracle of Apollo, the most important sacred site in ancient Greek religion. Nearby is the Sanctuary of Athena, which includes the Tholos pictured above. The archaeological site also includes the excellent Delphi Museum.
For the ancient Greeks, Delphi was quite literally the center of the world. According to Greek myth, Zeus released two eagles from opposite ends of the earth and they met in the sky above Delphi. Impaling one another with their beaks, they fell to the ground on the very center of the world. The site was marked by the Omphalos, or "navel" stone, a Roman copy of which can be seen in the Delphi Museum.
According to legend, the serpent Python was the ancient guardian of Delphi's Castalian Spring before he was killed by Apollo. Python was the son of the Greek goddes Gaia, "Earth." And significantly, the name Delphi is related to "womb" (delphos). It is probable that an Earth Goddess was originally venerated at the site before Apollo arrived.
Regarded as the center of the world and the dwelling place of Apollo, Delphi attracted pilgrims from across the ancient world. Generals, kings, and individuals of all ranks came to the Oracle of Delphi to ask Apollo's advice on the best course to take in war, politics, love and family. After the inquirer made a sacrifice, a woman known as the Pythia uttered cryptic pronouncements which were then translated by a priest.
