In ancient Greece the most important religious destination was the oracle of Delphi, dedicated to the god Apollo. The ancient Greeks considered the centre of the world to be there. Pilgrims from the Greek cities all over the Mediterranean gathered to ask for God's enlightenment, which was given by Pythia, the highest priestess of Apollo's Temple, in such a way that everyone could interpret it as they wished.
One of the most famous anointings was the one given to the Athenians shortly before the Persian invasion on how to protect themselves. The Oracle told them to build wooden walls ... So Themistocles persuaded them to build a navy (wooden walls-wooden ships) with which they finally destroyed the Persian fleet!
Around the temple of Apollo, constructions were built for the pilgrims, such as a theater, a stadium and a series of tributes from the autonomous cities of ancient Greece but also from kings and eminent Greeks. Today this archeological site impresses visitors who flock from all over the world.
