Delphi (/ˈdɛlfaɪ/ or /ˈdɛlfi/; Greek: Δελφοί, [ðelˈfi]) is a town in Phocis, Greece, situated immediately west of the archaeological site of the same name. It was created as a home for the population of Kastri, which was relocated to allow for the excavation of the site of ancient Delphi. The importance of the twin locations grew to the point where Delphi has also been made the name of the modern-day municipality, which includes the communities of the Pleistos 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.
