Last time we had cards from Ondrej in the Czech Republic, today I have a card from Ondras in Turkey. This card shows Pamukkale, a UNESCO site in Turkey:
“Pamukkale” means “cotton castle” in Turkish, although the cotton-like formations are in fact made of travertine, a form of limestone. The area has many hot springs and thermal pools. The calcium carbonate that is in the water is deposited, forming the cascading rock. There are similar deposits at other UNESCO sites in Yellowstone National Park (USA) and Huanglong (China).
Pamukkale is a mixed cultural and natural UNESCO site because, in addition to the natural beauty of the travertine formations, it is the site of the ancient Greek/Roman/Byzantine city Hierapolis, which was built on top of the rocks. The city took advantage of the hot springs; it was founded as a spa town in the 2nd century BCE.
Ondras used these two stamps on the card. I am not sure what is pictured on them. Perhaps someone familiar with Turkish stamps might help?
