The Ancient Theatre of Epidaurus was dedicated to the ancient Greek God of medicine, Asclepius. It is built on the west side of Cynortion Mountain, near modern Lygourio. It is considered to be the most perfect ancient Greek theatre with regard to acoustics and aesthetics. Because of its exceptional architecture and aesthetics, the theatre was inscribed on the UNESCO World Heritage List in 1988 along with the Temple of Asclepius.
According to Pausanias, the ancient theatre was constructed at the end of the 4th century BC, circa 340-300 BCE, by the architect Polykleitos the Younger. At a maximum capacity of 13,000 to 14,000 spectators, the theatre hosted music, singing and dramatic games that were included in the worship of Asclepius. It was also used as a means to heal patients, since there was a belief that the observation of dramatic shows had positive effects on mental and physical health.
Today, the monument attracts a large number of Greek and foreign visitors and is used for the performance of ancient drama plays.
The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
