Delphi would surely have also made the list of antiquity’s most awe-inspiring landscapes. Even today, its setting alone makes it worth the pilgrimage. The ruins run horizontally and vertically on the south-facing slope of Mount Parnassos, one of Greece’s highest mountains, and overlook one of its largest olive groves, with the Gulf of Corinth in the background. The pilgrims would purify themselves in the famous Castalian spring at the foot of the dizzying red-gold cliffs of Phaedriades.
