In Türkiye, the town of Pamukkale is known as the Cotton Castle, thanks to the area’s natural travertine (a type of limestone) rock formations that decorate the mountains. Natural hot springs have formed within these travertine terraces, where tourists flock to bathe in the mineral rich waters.
Located just below the ancient Greek city of Hierapolis, where temple ruins still stand today at a UNESCO World Heritage protected archaeological site. Hierapolis and Pamukkale have been well known for thermal pools since at least the 2nd century B.C., and people looking for healing and relaxation have been gathering here for thousands of years.
