Heirapolis/Pamukkale is the site of an ancient Hellenistic and then a Roman city because it benefits from a rejuvenating spa of constantly warm water that the ancients were rather fond of.
The source of the spring is carefully locked behind bars because as it emerges from the earth’s core it brings with it a lethal cocktail of poisonous toxic gasses that will overcome and kill in seconds but once separated from the noxious fumes the clear water flows down towards the edge of the mountain where it calcifies and forms startlingly white travertine pools of dazzling white calcium deposits like a fresh fall of snow that you mind find in Archangel, Alaska or Alberta.

How I wish I’d kept all the entrance tickets I’ve had, but I suppose they would have had to be thrown out when I down-sized. Lovely seeing all yours though.

Pamukkale looks amazing in some photos and I’d have liked to see for myself. 🙂 🙂 What happens to the toxic fumes then? And have you got white stuff of your own right now, Andrew?

Never touch the stuff Jo!
Toxic fumes probably like exhaust emissions they just get wafted away into the atmosphere.
