Aizanoi, Latinized as Aezani, was a Phrygian city in western Anatolia. It was located at the site of the modern village of Çavdarhisar, near Kütahya, on both sides of the Penkalas river, c. 1,000 m above sea level. The city was an important political and economic centre in Roman times; surviving remains from the period include a well-preserved Temple of Zeus, a combined theatre-stadium complex, and a round building, probably a macellum, inscribed with a copy of the Price Edict of Diocletian.
