Its site is located near Yeşilhisar in Asiatic Turkey. This site is located on the southwest flank of the Ahır Dağ, 84 km south of Kütahya. The only remains of the ancient settlement are a few old inscriptions and a capital dated to the early Byzantine period. The old name "Diokleia" is preserved in the nearby place called Dolay, or Doğla, a short distance to the south.
