The Alhambra 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. Converted into a royal palace in 1333 by Yusuf I, Sultan of Granada, it is now one of Spain's major tourist attractions, exhibiting the country's most significant and well-known Islamic architecture, together with 16th-century and later Christian building and garden interventions. The Alhambra is a UNESCO World Heritage Site and the inspiration for many songs and stories.
