Termessos (or Thermessos) was a Pisidian city built at a height of 1050 meters in the Taurus Mountains (modern day Antalya province, Turkey). Termessos constitutes an unusual synthesis of a large number of rare plants and animal species, which are under protection in the Termessos National Park.
Termesos is one of the best preserved of the ancient cities of Turkey. 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, which average only 200 metres above sea level. Concealed by a multitude of wild plants and bounded by dense pine forests, the site, with its peaceful and untouched appearance, has a more distinct and impressive atmosphere than other ancient cities. Because of its natural and historical riches, the city has been included in a National Park bearing its name.
