Today you'll visit the most popular achaeological site in all of Greece - the ancient 'Centre of the World' Delphi. This sanctuary was determined by the ancient Greek god Zeus who sent two eagles flying from opposite ends of the Earth. Where they crossed paths was the site of Delphi and so this was considered the centre of the world in ancient times. This UNESCO World Heritage Site is an extensive collection of ancient ruins, including the Temple of Apollo, dedicated to the son of Zeus, the treasury of Athens and the ancient theatre of Delphi. You'll explore the site, including the museum, before enjoying free time later on in the day.
