The ancient theater of Argos is the top cultural monument of Argos, located in a central part of the city, southeast of the hill of Larissa, stretching directly opposite the ancient market of Argos.
Constructed by Polykleitos in the late 5th century BC, the ancient theater of Argos is considered an architectural achievement, as a third is carved into a natural rock.
With a capacity of about 20,000 spectators in its years of prominence, the ancient theater of Argos is one of the largest ancient theaters in the Greek world, hosting musicals and dramatic races of Nemes, as well as races in honor of the goddess Hera, while during the Roman times the games which took place in the area was done in honor of the emperor.
