Sillyon, a city of Pamphylia, is built on a hill with almost entirely steep slopes and a flat top. It is located 16 kilometers from Serik district center and 30 kilometers from Antalya city center. Like all other Pamphylia cities, Sillyon is generally accepted to have been founded by the heroes named Mopsos and Calchas after the Trojan War. The ancient city of Sillyon, where the Hellenistic city ruins are the densest within the borders of Antalya province, is also the city where Hellenistic defense is best represented. To visit Sillyon, you should be prepared for a challenging climb. However, the views you will see at the end of the promotion will be worth all this trouble.
