Doric columns of the Temple of Apollo. Constructed in the 4th century BC over the ruins of earlier sanctuaries, this legendary structure was the home of the famed Oracle of Delphi, where the high priestess Pythia channeled cryptic divine prophecies that shaped the course of empires. Discovered and partially reconstructed during the extensive 19th-century French excavations, the temple's stone ramp and remaining pillars are a profound monument to ancient spiritual devotion.
