Pamukkale Water Terraces - Denizli, Turkey

Romans knew a lot about about comfort and luxury. The Pamukkale Water Terraces are formed from white travertine and were used in the Roman-era as a spa in the city of Hierapolis. Water from ancient hot springs still spills down the hillside into the naturally formed, oyster-shell shaped terraces and pools. The calcium rich, healing waters are still appreciated today, although the area is now a protected UNESCO World Heritage Site.
