Luna castle dates from the 13th century and was built under control of 'Guzmán the Good' upon a fortified convent of ribat or Muslim origin, in the 11th century. It is rectangular with five crenelated towers, and its interior is structured around a central courtyard.
Property of the Dukes of Arcos, the Ponce de León used the castle as a residence and there is evidence that the Catholic Monarchs visited the city and stayed there.
The Luna Castle is a symbol in itself for citizens of Rota, Cadiz, and proof of this is its presence on the coat of arms of the village. It has housed a hospital and a school, and is currently the location of the City Hall of Rota.
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.
