Delphi Archaeological Site

The UNESCO World Heritage Site at the foot of Mount Parnassus was considered by the ancient Greeks to be the center of the world (omphalos), marked by a stone navel, and its Oracle -- a priestess (Pythia) who inhaled ethylene gases emerging from a geological fissure -- was consulted by leaders from Croesus to Alexander the Great for 1,000 years from 800 BC to 390 AD. The site contains the Temple of Apollo, a 5,000-seat theatre, and the Delphi Museum housing the 478 BC Charioteer of Delphi -- one of the finest surviving bronze statues from antiquity.
