Alhambra

The Alhambra (from Arabic = Al-Ħamrā', literally "the red fort"; the complete name was = al-Qal'at al-Ħamrā' = "the red fortress") is a palace and fortress complex of the Moorish rulers of Granada in southern Spain (known as "Al-Andalus" when the fortress was constructed during the mid 14th century), occupying a hilly terrace on the southeastern border of the city of Granada.
History.
In the Middle Ages the Alhambra was the residence of the Muslim rulers of Granada and their court, now it is one of Spain's major tourist attractions. There one can see the most famous Islamic Architecture of the country. Within the Alhambra, the Palace of Charles V was erected by Charles V, Holy Roman Emperor in 1527.
The Muslim rulers lost Granada and Alhambra in 1492 without the fortress itself being attacked when King Ferdinand II of Aragon and Queen Isabella of Castile took the surrounding region with an overwhelming force of numbers.
