8. Pamukkale Travertines: A Natural and Cultural Monument in the World Heritage List

The actively accumulating Pamukkale travertines and the ancient city of Hierapolis are located along the northern margin of the Denizli Basin in Western Turkey and are both included as a mixed natural and cultural property in the World Heritage List. Travertine terraces and pools (terraced-mound travertines) attract visitors to Pamukkale, but fissure-ridge travertines and self-built channel travertines are as attractive as terraced-mound travertines and they should be considered as natural monuments. In addition to major ancient buildings in the city centre of Hierapolis, there are other ancient structures such as quarries, water channels and aqueducts in the Pamukkale area. In order to save these natural monuments and cultural heritages for future generations, boundaries of the existing preservation plan should be enlarged immediately to cover all travertine bodies and cultural structures in the Pamukkale region.
