On a slope above the rest of the Hierapolis ruins is the mighty theater, with its facade over 100 meters long and two tiers of seating, each with 26 rows.
Built during the reigns of the Roman Emperors Hadrian and Septimius Severus, the theater is incredibly well-preserved. It has retained much of its original detail, with the imperial boxes (where VIP guests would have watched the entertainment) and some decorative panels along the stage still surviving.
