In 955, Almería gained the title of medina ('city') by the Caliph of Cordoba, Abd ar-Rahman III: construction of the defensive citadel, located in the upper sector of the city, began in this period. The alcazaba, provided not only with walls and towers but also with squares, houses and a mosque, was to be also the seat of the local government, commanding the city and the sea nearby.
The complex was enlarged under caliph Al-Mansur and, later, under Al-Jairan, first king of the independent taifa of Almería (1012–1028).
The first line of walls is a wide enclosure corresponding to the first Muslim military camp, used as shelter for the population in case of siege. For this task it was provided with large cisterns.
The first enclosure is separated by the second one by the so-called Muro de la Vela ('Wall of the Sail'), taking its name from a bell that warned the population in case of events such as the arrival of a ship in the port, danger, fires etc. This wall was built by King Charles III of Spain.
In the second enclosure was the residence for the governors, their soldiers and their servants. It included also the mosque, baths, tanks, tents etc.
The third enclosure, the most external, is also the most modern in the complex. After the Christian conquest of Almería, the Catholic monarchs Isabella I of Castile and Ferdinand II of Aragon had a castle built in the most elevated sector of the town, more apt to resist the new gunpowder artillery.
References:The first written record of church in Danmark locality date back to the year 1291. Close to the church are several stones with a Christian text and cross inscribed. The oldest parts of the present red-brick church are from the 1300s. In the late 1400s the church was enlarged to the appearance it has today. The church has been modified both internally and externally several times, among other things after the fires in 1699 and 1889. There are lot of well-preserved mural paintings in the walls.
