Cestria or Kestria (Ancient Greek: Κεστρία),[1] also known as Ilium or Ilion (Ἴλιον), or Troja (Τροΐα),[2] was a town in ancient Epirus.[3] Its district was called Cestrine or Kestrine (Κεστρίνη) and Kestrinia (Κεστρινία),[4] and was located in Chaonia, separated from Thesprotia by the river Thyamis.[5] It is said to have received its name from Cestrinus, son of Helenus and Andromache,[6] having been previously called Cammania or Kammania (Καμμανία).[7] The principal town of the district was Cestria,[8] but its more usual name appears to have been Ilium or Troja, in memory of the Trojan colony of Helenus.[9] In the neighbourhood are those fertile pastures, which were celebrated in ancient times for the Cestrinic oxen.[10] The inhabitants of the district were called Κεστρηνοί by the poet Rhianus.[11]
The city is located near the modern Filiates, Greece.[12]
