The Cartama Castle is located in the Monte de la Virgen (Mount of the Virgin), where the Hermitage of Nuestra Señora de los Remedios is also located and where it is possible to be enjoyed some impressive panoramic views. Cártama Castle was built by the Moors in the early Middle Ages. During the Mozarabic revolt of Omar ibn Hafsun, between 881 and 914 AD, Cártama stayed loyal to the Caliphate of Córdoba and the castle was strengthened.
Because of the advancing Christian troops Cártama Castle was again strengthened during the 14th century. By that time the castle would probably have had a double curtain wall and several towers. In 1485 however, the castle was taken by Christians troops. Because the castle was important for their siege against the city of Málaga the Catholic Monarchs invested large sums of money in maintaining the castle between 1485 and 1487. From 1491 on the castle lost its strategic importance and the castle was used as a quarry by the locals.
What you can see today are the scarce remains of a rectangular alcazaba with its surrounding walls and a cistern.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
