On the Greek mainland, Delphi is a UNESCO World Heritage site. Built on the lower slopes of Mount Parnassus, overlooking a dramatic ravine, the site was sacred to the ancients, who came here on pilgrimages to worship Apollo (god of light, prophecy, music, and healing) and to ask advice from the mythical Oracle. It is made up of the crumbling ruins of numerous temples, a theater, and stadium, dating from between the 8th century BC and the 2nd century AD. Nearby, stands the Delphi Museum Archaeological Museum, displaying an impressive collection of finds from the site. Delphi lies 180 kilometers northwest of Athens.
