Perched above the travertines of Pamukkale sits the ancient ruined city of Hierapolis. Listed as a UNESCO World Heritage Site, there is not a lot known about its origin. Pamukkale’s hot springs gave this city life, as people had been curing their ailments in the ‘spa’ since the second century BC. Situated onsite is a large necropolis filled with sarcophagi, including that of the great Marcus Aurelius Ammianos.
