The theatre at Hierapolis was built in the second century AD under the Roman Emperor Hadrian during a period of extensive rebuilding following a devastating earthquake in 60 AD. It was later renovated under Septimus Severus (193-211 AD). At this time, the scaenae frons was modified and decorated with elaborate limestone and marble carvings. Although the exterior is relatively unassuming as viewed from the front, the interior contains one of Anatolia’s most complete and best-preserved collection of Greco-Roman theatre decorations. In 343 AD the scaenae was renovated and the orchestra was altered so that it could hold aquatic displays. In the later years of the Roman Empire the orchestra was converted into a cellar. Renovation work since 1977 has restored many of the arches and a portion of the stage floor. Prior to this date, the stage as well as its arched support system lay in ruins. Recent archaeological evidence shows that the theatre was in use through the 5th and into the 6th century AD. In 532 AD the scaenae, which had been weakened by seismic activity, was repaired.
