The Alcazaba is a palatial fortification in Málaga, Spain. It was built by the Hammudid dynasty in the early 11th century. This is the best-preserved alcazaba (from the Arabic al-qasbah, قصبة, meaning "citadel") in Spain. Adjacent to the entrance of the Alcazaba are ruins of a Roman theatre dating to the 1st century BC, which are undergoing restoration. Some of the Roman era materials were reused in the Moorish construction of the Alcazaba.
