Segesta (Sicilian: Seggesta) was the political center of the Elymian people. It is in the northwestern part of Sicily, in the province of Trapani and in the comune of Calatafimi-Segesta. According to the tradition used in Virgil's Aeneid, Segesta was founded jointly by the territorial king Acestes (who was son of the local river Crinisus by a Dardanian woman named Segesta or Egesta) and by those of Aeneas' folk who wished to remain behind with Acestes to found the city of Acesta.
