Ariassos or Ariassus was a town in Asia Minor built on a steep hillside about 50 kilometres inland from Attaleia .HistoryThe town was founded in the Hellenistic period in the 3rd century BC. It was mentioned (as Aarassos) in about 100 BC by Artemidorus Ephesius, who was quoted by Strabo a century later. The only further mentions are by Ptolemy in the 2nd century AD and in lists of Christian dioceses.It was part of Pisidia, and belonged originally to the Seleucid Empire. In 189 BC it passed to the hellenistic kingdom of Pergamum, the last king of which, Attalus III left his kingdom the Rome in 133 BC. Under Octavian Augustus, Ariassos was made part of the Roman province of Galatia. In the ecclesiastical lists it appears in the late Roman province of Pamphylia Secunda, whose capital was Perge, hence also its bishopric's Metropolitan.RemainsCoins minted at Ariassos are extant.The ruins are mainly of Roman and Byzantine times, with few remains of the earlier Hellenistic period. The best preserved is that of the 3rd-century-AD triple-arched city entrance once surmounted by four statues. Other building include an extensive nymphaeum and baths, as well as a large domestic area. There is an abundance of funerary monuments.
