The Castle of Lanjarón, locally known as the Moorish Castle, is a small medieval fortress located a quarter mile from the village. It is dominating on a rocky outcrop, the valley of the Lanjarón River, next to the Salado canyon. It is formed by two enclosures with some small sections of the outer wall. Signs of a tower are preserved; a bastion square, masonry at its bottom and above a adobe. At the south of the complex is an underground cistern, covered with a vault of brickwork.
Lanjarón castle was built between the 13th and 16th centuries in the late Moorish age and restored by Christians later.
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.
