Denizli & Pamukkale & Travertines
TRAVERTINES
The sources of thermal water for Pamukkale are about 20 km from Denizli. The ancient city of Hierapolis is also located in the same place. The water comes from underground karstic caverns and creates the cascades through precipitation of CaCO3 (calcium bicarbonate ) as the CO2 (carbon dioxide) evaporates.
Thermal spring water is beneficial for myocardium and cardiac complaints.The curative value of this thermal spring was understood in ancient times as well. It has been used for centuries. During the Roman Era religious ceremonies and festivals were held at the thermal pools, and important statesmen and rich people came to Hierapolis to be cured. Religious functionaries and ancient physicians administered healing.
