Ancient Hierapolis appears to have been founded by King Eumenes II of Pergamon and its name is derived from Hiera, the wife of King Telephos, the legendary founder of Pergamon. The city became subject to Rome in 133 B.C. In 17 B.C. during the reign of Tiberius it suffered a heavy earthquake that substantially destroyed the city, requiring it to be rebuilt.
Preliminary excavations at Hierapolis were undertaken by a German team towards the end of the last century. Since 1957, excavation and restoration work has been going on under the direction of an Italian group of archaeologists.
