The modern town of Delphi is situated immediately west of the archaeological site of the same name. The town was created as a home for the population of Castro, which was to be removed to daylight the site of ancient Delphi. The importance of the twin locations grew to the point where Delphi has been made the name of the modern-day municipality, which includes the communities of the Plaistos valley system as far south as the Gulf of Corinth. The name Delphi came from the Oracle of Delphi, which was anciently accepted as a purveyor of truth revealed by the god Apollo.
