The Alcázar of the Caliphs or Caliphal Alcázar, also known as the Umayyad Alcázar and the Andalusian Alcazar of Cordoba, was a fortress-palace located in Córdoba, in present-day Spain. It was the seat of the government of Al-Andalus and the residence of the emirs and caliphs of Córdoba from the 8th century until the 11th century and the residence of local Muslim governors from the 11th century until the Christian conquest in 1236.
