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 in Spain. Adjacent to the entrance of the Alcazaba are remnants of a Roman theatre dating to the 1st century BC.
Some of the Roman-era materials were reused in the Moorish construction of the Alcazaba. Ferdinand and Isabella captured Málaga from the Moors after the Siege of Málaga (1487), one of the longest sieges in the Reconquista.
