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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
