The Angevin-Aragonese castle in Agropoli has a triangular shape with three circular towers and stands on the highest point of the headland. Around the walls there is a wide and deep moat which today is visible just on the side of the village and disappears while on the eastern side because of agricultural works and past landslide.
The castle was built on the 6th century Byzantine foundations by the Aragonese reign in the 15th century. The Inside part of the castle is composed of a central square, nowdays used as on open air theater, and on the northern side by the “French Room”.
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.
