Aspendos
The ancient city of Aspendos is located 40 km east of Antalya, on the Köprüçay River, which in antiquity was called the Eurymedon. Eurymedon River was famous in ancient times because of the Battle of the Eurymedon in the 5th century BCE between the Greeks and their allies and the Persian Empire of Xerxes I. The battle is known as the first battle that took place both on water and land.
Today, the site is primarily famous for the splendid Roman theatre known as the best-preserved and best-designed theatre of the Mediterranean during the Roman period. Following the theatre, the most important city ruins that can be visited are the aqueducts. The Aspendos aqueduct system is also one of the best-preserved examples of ancient waterways. Other important structures include the great basilica, the agora, the fountain, the aqueducts, and the two unique siphon systems which have been a source of fascination for archaeologists.
