Pamukkale - Hieraoplis

Pamukkale is one of the most interesting places famous not only for the entrancing beauty of its unique geological formations but also for its historical remains. The calcium oxide-rich waters flowing down the southern slope built up deposits of white travertine on the plateau thus fully justifying both the site's ancient name of Hierapolis (Holy City) and its modern one of Pamukkale (Cotton Castle).

And the minerals in the water seem to have an effect on us tourists too...
