The theater of ancient Aptera is located on the southern wall of the ancient city, near its southeastern entrance. Its current form belongs to the Roman phase and arose after a radical reconstruction of the earlier Hellenistic theater. The pews were repositioned on a brick plinth, while the stage was replaced by a more imposing Roman one.

In later years, a lime kiln was built in the middle of the hollow, which altered the construction of the theater. Its builders had incorporated architectural elements of the theater, while the limestone benches were the raw material for the preparation of lime. The hollow, 54.68 m in diameter, corresponded to 26 rows of seats. Today, 43 pews survive in their place, in stepped mudstone construction, and part of the central staircase. Also, the 13 lowest foundation levels due to newer leveling operations for field cultivation have been exposed. The appearance of the stage is formed by three large niches, which corresponded to three doors, while east and west of the foreground were formed the backstage. Today, maintenance and excavation work has been carried out by the relevant Archaeological Service.
