Hierapolis, Pamukkale, Turkey
The chalk-laden hot springs of Pamukkale in south-western Turkey, near Denizli is a magnificent sight to behold. The white layers of limestone and travertine looks like waterfall that has been frozen in time. At the top of this “cotton castle” the ancient city of Hierapolis.
