The Alhambra, the complete Arabic form of which was Qalat Al-Hamra, is a palace and fortress complex located in Granada, Andalusia, Spain. It was originally constructed as a small fortress in AD 889 on the remains of Roman fortifications, and then largely ignored until its ruins were renovated and rebuilt in the mid-13th century by the Moorish emir Mohammed ben Al-Ahmar of the Emirate of Granada, who built its current palace and walls.
