Pamukkale (Cotton Castle)
Pamukkale, meaning “cotton castle” in Turkish, is an unreal landscape in western Turkey, famous for its white terraces. The terraces are made of travertine, a sedimentary rock deposited by water with a very high mineral content from the hot springs. People have bathed in its pools for thousands of years. The ancient Greek city of Hierapolis was built on top of the hot springs by the kings of Pergamon. The ruins of the baths, temples and other Greek monuments can be seen at the site.
