Castellar de la Frontera is a village within a castle surrounded by the walls of a well preserved Moorish-Christian fortress. It is located within the Parque Natural de Los Alcornocales next to a reservoir formed by the Guadarranque River.
The history of the village goes back to prehistoric times and the Bronze Age, after which the place became a medieval fortress. The prehistoric presence is still evident in the many caves around the area, where enthusiasts can see the wonderful cave drawings as proof of its heritage. It played an important role in the wars between the Spanish and the Muslims. In such a high up advantageous strategic position, peoples of many cultures wanted to control this strong vantage point.
The village was conquered and won back between Fernando III, the Moors and then Juan II, who described it as 'such a wonderful, strong town'. After the many battles of medieval times, by October 1650 Teresa María Arias de Saavedra, the Countess of Castellar, took possession of the town and later it was in the hands of the Medinaceli family.
The village was abandoned in the 1970s and its inhabitants moved to the aptly named Nuevo Castellar. The derelict state of the village attracted a number of Germans who took over the empty houses and built temporary dwellings outside the walls. The village was later repopulated.
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.
