Aizanoi (Ancient Greek: Αἰζανοί), Latinized as Aezani was an ancient city in western Anatolia. Located in what is now Çavdarhisar, Kütahya Province, its ruins are situated astride the River Penkalas, some 1,000 m (3,300 ft) 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, unusual combined theatre-stadium complex, and macellum inscribed with the Price Edict of Diocletian. The city fell into decline in Late Antiquity. Later serving as a citadel, in 2012 the site was submitted for inscription on the UNESCO World Heritage List.
