The Alcazaba, Castle and Walls of the Cerro de San Cristóbal of the Spanish city of Almeria is one of the most important Andalusian monumental and archaeological sites of the Iberian Peninsula. Its almost thousand years of history has allowed us to know the evolution experienced in civil and military architecture during the Arab domination in Al-Andalus,due to its construction in different phases and eras, such as the castle and towers of the Christian bajomedieval period (XV -XVIcenturies),as well as the origin and evolution of the city (with a perimeter in total of the entire fortification, according to the Tourist Office of Almeria, of 1430 meters,counting the bajomedieval castle, the citadel preserved today and the rest of the outer walls)
