Sillyon

Sillyon, in Byzantine times called Syllaeum or Syllaion (Συλλαῖον), was an important fortress and city near Attaleia in Pamphylia, on the southern coast of modern Turkey. The native Greco-Pamphylian form was Selywiys, possibly deriving from the original Hittite Sallawassi. Its modern Turkish names are Yanköy Hisarı or Asar Köy. (Wikipedia)
