Aspendos or Aspendus (Greek: Ἄσπενδος) was an ancient Greco-Roman city in Antalya province of Turkey. It is located 7 kilometres (4.3 mi) northeast of central Serik.Aspendos was an ancient city in Pamphylia, Asia Minor, located about 40 km east of the modern city of Antalya, Turkey. It was situated on the Eurymedon River about 16 km inland from the Mediterranean Sea; it shared a border with, and was hostile to, Side. According to later tradition, the (originally non-Greek) city was founded around 1000 BC by Greeks who may have come from Argos. The wide range of its coinage throughout the ancient world indicates that, in the 5th century BC, Aspendos had become the most important city in Pamphylia. At that time the Eurymedon River was navigable as far as Aspendos, and the city derived great wealth from a trade in salt, oil, and wool.
