Delphi

In myths dating to the classical period of Ancient Greece, the site of Delphi was believed to be discovered by Zeus when he sought to find the centre of his "Grandmother Earth" or Gaia. He sent two eagles flying from the eastern and western extremities, and the path of the eagles crossed over Delphi where the omphalos, or navel of Gaia was found. Occupation of the site at Delphi can be traced back to the Neolithic period with extensive occupation beginning in the Mycenaean period. Most of the ruins that survive today date from the 6th century BC.
