The history of the thermal spring dates back to the Lydian Kingdom and gains its name from the sediments present. Today, the water of the spring is left to rest. And, after the sediment is precipitated, the hot water is used in the thermal baths. The water stemming from the thermal spring has a temperature of 52ºC. There is a bazaar near the bath where the local products are sold. A significant thermal facility exists near the spring.
