Birgi is a small town located in the Ödemiş district of İzmir province in Turkey. Its current name is a distortion of its medieval Greek name, Pyrgion (Greek: Πυργίον, meaning "Little Tower").In antiquity, the town was known as Dios Hieron (Διός Ἱερόν, "Sanctuary of Zeus"). It was renamed to Christoupolis (Χριστούπολις) in the 7th century and was known as Pyrgion from the 12th century on.
