Aspendos Ruins and Theater

Aspendos was an ancient Greco-Roman city founded around 1000 B.C. It was located about 25 miles from the modern city of Antalya, and it's known for having one of the best preserved theaters from antiquity. Despite being built in 155, the theater is still in great shape and has remained mostly intact. A small portion of the theater was built leaning into a hill where the Acropolis stood, and the rest of it was built on vaulted arches. A sloping wooden ceiling that was over the stage area has been lost over time. Dozens of post holes are on the upper level, which at one time supported an awning to protect the audience from the sun. 
Since the theater is still in such good condition, it is still a functional venue. The Aspendos International Opera and Ballet Festival holds annual productions in the theater in the spring and early summer. 
Spend some time wandering around outside the theater as well. Nearby you'll find the ruins of a basilica, the agora, a nymphaeum, and more than nine miles of a Roman aqueduct. You can also find the Eurymedon Bridge. This was a Roman era bridge that was rebuilt in the 13th century.
