Ancient Delphi, perched high on the slopes of Mt. Parnassos, was not a city. It was the site of the oracle of Apollo, god of the sun. People would journey here from all over the known world to seek wisdom from the gods on vital affairs of state. Tourists today zig-zag up the ancient Sacred Way to the Temple of Apollo. The path is flanked by the remains of Delphi's famous treasuries — monuments erected by city-states in gratitude for the oracle's advice.
