Encinas Castle is dated back to the 14th century. The castle consists of a small and square enclosure, with two square towers in two of its corners. One of these served as the keep. In the other two corners the crenelated walls are raised to the same height as the two towers thus giving the false impression that the castle had four towers. There is a small stone ditch at the feet of the walls, which is provided with a low defensive wall.
In the 1950's the ruined castle was acquired by the Ministry of Agriculture. They restored it and turned it into a cereal silo. During these restorations however they blinded original windows and totally destroyed its medieval interior.
References: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.
