added by archaeologs Ancient city of Sicily, north of modern Calatafimi, which was the chief city of the Elymi. The Elymi may have been of Trojan origin; they are archaeologically indistinguishable in the Early Iron Age (c 1000-500 BC) from their Sicanian neighbors. Segesta had a Greek culture, but it often sided with the Carthaginians against its Greek neighbors (mainly Selinus). Early in the First Punic War, Segesta massacred the Carthaginian garrison and allied themselves with Rome. It became a free city under Roman rule. Segesta ruins include an unfinished 5th-century BC temple and a Hellenistic theater. The city site is on the plateau adjacent to the theater. The surviving 5th-century temple, which stood outside the original city, is usually seen as a distinguished, but unfinished example; it has a colonnade, but no interior cella.
