Sagalassos theatre is one of the highest theatres in the world along with the upper theatre of the ancient city of Balboura in Altınyayla. What remains of the theatre is dated to 180-200 B.C. The stage edifice of the two-tier theatre is mostly intact. The ruins, which have collapsed over the course of time, remain in a heap in the orchestra pit. While the left side of the cavea almost totally leans on the hillside, some parts of the right hand side rest on the support wall encircling it. From the vaulted walkway under the second echelon, the central walkway can be reached through 12 exits. These exits are four feet wide and six feet high. The central walkway is eight feet wide, and the support wall next to it is eight feet and four inches high. In order to reduce the effect of the void created by the central walkway, stone benches with backboards arranged along the boundary are also used here. The horseshoe-shaped orchestra has a radius of 36 feet and 4 inches. The stage edifice is estimated to be 49 feet high. The cavea faces southwest from a height of 1,575 m. There are 24 rows of benches in the first echelon and 15 rows of benches in the second echelon. There are 12 radial walkways in the first echelon. The radial walkways were created after the rows of benches were carved out of the rock. The holes cut into the benches for the shading poles inclining to the front are quite visible.
Sagalassos theatre has a capacity of approximately 7,000 people.
