Hierapolis is an ancient city located on the top of Pamukkale and is a World Heritage site. There is a mixture of Pagan, Roman, Jewish and early Christian influences. Since the hot springs of Pamukkale were used as a spa since the 2nd century, people came to Hierapolis to soothe their ailments and often retire and die. The ruins sprawl over a large area and there is a large necropolis filled with sarcophagi.The baths were made from large stone blocks and there are various open and closed areas linked together. The complex was constructed in the 2nd century and there are few historical facts known about the origin of the city. Many of the statues were transported to museums across the world and in 1970 a museum was built onsite.
