Those who read my Truskavets series from a couple of years ago (starting here) will know I am not entirely sold on miraculous cures from "taking the waters". The water at Pamukkale is touted as curing everything external or internal. Judging from the mineral content it should certainly cure constipation. The Romans knew a good thing when they saw it ie people who think spas are useful must have money and should be parted from it as soon as possible. Modern Turkey is onto it as well. Going into the hot pool in Hieropolis is $18. It reminded me of a fish farm. The Romans built on top of the hill as it was the source of hot water and easier to defend. The Turkish spa town of Pamukkale is at the bottom of the hill to escape UNESCO.
