The Alcázar de los Reyes Cristianos (Spanish for ‘Castle of the Christian Monarchs’, also known as the Alcázar of Córdoba) is one of the most significant historic buildings in the city of Córdoba. Home to both Moorish and Christian monarchs, the Alcázar also served as the headquarters of the Spanish Inquisition in Córdoba for several centuries. The fortress itself is a beautiful example of Mudéjar architecture, and is surrounded by even more stunning gardens.
