It’s about 20 km north of Denizli. It is called a Holy City in Archeological literature because there were many temples and religious buildings in Hierapolis. The ancient city is situated between several historical areas. According to the ancient geographers, Strabon and Ptolemaios, Hierapolis was very close to Laodicea and Tripolis which was in Kario’s Border. That’s why it was a Phrygian City. There is no information about Hierapolis’ history before the Hellenistic Era, but we know there was a city there before then. It’s called Hierapolis because of its Mother goddess Cult.
Information about Hierapolis is limited. It is known that the king of Pergamum, Eumenes II, founded the city in 190 BC. It was named Hierapolis after the Amazon’s Queen Hiera, the wife of Telephos, the founder of Pergamum. (Pergamum is also called Pergamon or Pergamos).
Hierapolis was destroyed by the earthquake in 60 A.D. during the time of Roman Emperor Nero. During the reconstruction after the earthquake, the city lost its Hellenistic Style and became a typical Roman City. Right after the Roman period started, Hierapolis became an important center because of its commercial and religious position. In 80 A.D. St. Philip came to Hierapolis and was murdered by the Jewish inhabitants. The Turks conquered Hierapolis at the end of the 12th century A.D.
