It is a Greco-Roman style theatre, built with its back leaning against the hill. In other words, it was erected before the Roman period, but works of repair and modification were performed later by the Roman.
As in the Greek style, Cavea was separated from the stage structure by the uncovered entrance sections (parados). However, the fact that the passageway (diazoma) dividing the cavea into two was seated on a gallery, which also provided entrance here from outside, and that the stage structure had multiple floors reflect the Roman character.
Having a seating capacity of 15.000 spectators, the cavea was divided into two by a diazoma. There are 23 sitting rows in the upper section, while the lower section hosts 19 sitting rows. As an advantage of the theatre’s location on the slope of the hill, the spectators were able to enter from the outside directly to diazoma, through an arched passage (vomitorium). There is a gallery on the back section of Cavea (Roman style), which connects to cavea by means of arched passages.
The flat place reserved to the orchestra is separated from the cavea with a 1,80 m. high wall. It is obvious that this was done to protect the spectators during the gladiator and wild animal fights of the Roman period.
The stage building is multi floored, with the lowest floor being a 50 m. long gallery. The date of construction for the stage building is 2. century A.D. Its side facing the spectators was richly decorated with five niches between the columns of each floor and the statues inside these niches. The statues decorating the walls of the theatre and the friezes bearing the description of mythological scenes are today exhibited in place and also in Antalya Archaeology Museum.
Five gates lead from the staff building (scenae) to the stage. The outer back wall of the stage building was later decorated with korinth style columns and niches, and it was thus converted to a monumental fountain (nymphaion).
