The Cotton Castle has nothing to do with any kingdom. It is a breathtaking natural wonder, which looks like frozen waterfalls but in reality is a white cliff covered with white minerals, left by the flowing down, hot water from an underground spring. This process has been running unstoppably for over 14000 years. Around the 2nd century BC, the ancient city of Hierapolis developed right above the cliff, making Pamukkale an ancient spa.
Ever since people discovered Pamukkale, they bathe in the natural pools, especially in the summertime. Nature didn't seem to be bothered by this fact and the terraces remained in almost untouched condition until the last century, when some modern hotels were built nearby and negatively affected the spring's natural processes.
I've seen the cotton castle two times. For the first time, I went to Pamukkale about 10 years ago with my parents. We were asked to take off our shoes, when entering the terraces. It was very painful for me to walk barefoot there. The day was very hot, the sky was extremely blue and the terraced pools were filled with water and people. There were soooo many of those pools within eyes reach. Also, I still have on my mind, what some local Turkish people told me, that it's not as beautiful as they remember it used to be.
The second time I went there was late April 2011, the temperature was bearable. I must say, that I was impressed by the new arrangements made around the entire area such as wooden paths. It surely protects those of the terraces that are left. However, the visitors are still allowed to step on them and bathe and do whatever they want in the selected areas. This time, I decided to keep my shoes on and not to participate in this act of destroyment, as I had my chance to take a few steps there before.
When I sat on one of the benches, I suddenly heard two older gentleman from Poland admiring the view few meters away from me. It sounded as if one of them was in Pamukkale in the 1960's and his impressions were just like mine from late 1990's, that there were hundreds of people bathing in the healing water.
I didn't notice when it got very late, I had to skip the ancient ruins and hurry not to miss my bus.
