The archaeological site of Menelaion is located approximately 5 km from the modern city of Sparta. The geographical structure of this site includes a hill complex (Northern hill, Menelaion, Profitis Ilias and Aetos).
Menelaion was a Mycenaean acropolis (founded 15th - 12th centuries BC), with a building that was built in three phases and probably had a palatial character. Count of the Achaeans, perhaps identical with the Sparta of the Homeric epic. In a place of perhaps prehistoric worship, on a hill, a sanctuary of Menelaus and Helen, who were worshiped here as gods, was founded in geometric times. Remains of two men with rectangular analemmas, one enclosing the other (6th and 5th centuries BC). Uphill access leads to the foundations of a rectangular temple inside.
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.
