Termessos was a Pisidian city built at an altitude of more than 1000 metres at the south-west side of the mountain Solymos in the Taurus Mountains. It lies 30 kilometres to the north-west of Antalya. It was founded on a natural platform on top of Güllük Dağı, soaring to a height of 1,665 metres from among the surrounding travertine mountains of Antalya.
The mythical founder of the city is Bellerophon.
What is known of Termessos' history commences principally at the time that Alexander the Great surrounded the city in 333 BC; he likened the city to an eagle's nest and in one of few cases, failed to conquer it.
From the main road, a steep road leads up to the city. From this road one can see the famous Yenice pass, through which wound ancient road that the Termessians called "King Street" as well as Hellenistic period fortification walls, cisterns and many other remains.
